Basic Installation
==================
EMAIL ID LEGEND:
Briefly, the shell command `./configure && make && make install'
should configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package. Some packages provide this
`INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.

The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
FOOTNOTES:
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
[1] Due to limitations in the Sun autofs v1 implementation, some amd features
cannot be properly supported. More precisely, trying to access a link mount
pointing to another amd entry will result in failure and/or deadlock.
Ordinary nfs and link mounts work well, however.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
[2] AIX autofs appears to be a variant of the Sun autofs v1 protocol, but
IBM don't provide any sort of documentation or even header files from it.
It is currently unsupported; we may add some experimental support for it at
some point, though it won't be pretty. Assistance from IBM-ers would be
highly appreciated, hint hint.
The simplest way to compile this package is:
[3] IRIX 6 autofs uses the Sun autofs v1 protocol, too. The header files
are part of the onc3_eoe.sw.autofs (IRIX 6.2) or nfs.sw.autofs (IRIX 6.5)
package, which may not be installed. The autofs code is known to compile,
but hasn't been run yet. SGI's autofsd uses a barely documented system
call, syssgi(SGI_AUTOFS_SYS, ...), which may be required to get working
autofs support. Additional help from SGI would be highly appreciated.
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Erez & Ion
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type `make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the `make install' phase executed with root
privileges.
5. Optionally, type `make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior `make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type `make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide `make
distcheck', which can by used by developers to test that all other
targets like `make install' and `make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'. This
is known as a "VPATH" build.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the
default for these options is expressed in terms of `${prefix}', so that
specifying just `--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to `configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
`make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, `make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
`${prefix}'. Any directories that were specified during `configure',
but not in terms of `${prefix}', must each be overridden at install
time for the entire installation to be relocated. The approach of
makefile variable overrides for each directory variable is required by
the GNU Coding Standards, and ideally causes no recompilation.
However, some platforms have known limitations with the semantics of
shared libraries that end up requiring recompilation when using this
method, particularly noticeable in packages that use GNU Libtool.
The second method involves providing the `DESTDIR' variable. For
example, `make install DESTDIR=/alternate/directory' will prepend
`/alternate/directory' before all installation names. The approach of
`DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of `${prefix}'
at `configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of `make' will be. For these packages, running `./configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with `make V=1'; while running `./configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with `make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
HP-UX `make' updates targets which have the same time stamps as
their prerequisites, which makes it generally unusable when shipped
generated files such as `configure' are involved. Use GNU `make'
instead.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
in your `PATH', put it _after_ `/usr/bin'.
On Haiku, software installed for all users goes in `/boot/common',
not `/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf limitation. Until the limitation is lifted, you can use
this workaround:
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of all of the options to `configure', and exit.
`--help=short'
`--help=recursive'
Print a summary of the options unique to this package's
`configure', and exit. The `short' variant lists options used
only in the top level, while the `recursive' variant lists options
also present in any nested packages.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names::
for more details, including other options available for fine-tuning
the installation locations.
`--no-create'
`-n'
Run the configure checks, but stop before creating any output
files.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

MAJOR BUG FIXES: Synchronize Amd's view of its file systems with the

@ -114,13 +123,82 @@ Amd.
Tell syslog not to log automatically to /dev/console; it's unfriendly. If
user really wants to, they can set it in /etc/syslog.conf.
Moved pawd's path-matching functionality into Amd, where it can be done a
lot more efficiently (we no longer need to construct and send the whole
mounted tree, only to match small parts of it). This will lessen the CPU
and network load on systems that use pawd heavily, and also minimize the
chance that we exceed default or hard-coded UDP/TCP RPC packet sizes.
Changed slightly how Amd behaves when you try to change log_options after
Amd started (options can be turned on/off via "amq -x ARG"). It used to be
that Amd won't let you turn off options which were on when Amd started.
That limited users' ability to reduce Amd's logging levels to a minimum.
Now, Amd will allow you to turn on/off any option, other than the two
options "fatal" and "error." Both are on by default and considered
mandatory. These two don't produce a lot of log messages, so your logs will
remain small, but they are important to keep on, so Amd can report serious
problems (including errors relating to incorrectly setting other log
options).
Amd now understands a new log_option called "defaults" which is synonymous
with "fatal,error,user,warning,info" (and is also what logging happens by
default).
Amd now understands a new debug_option called "defaults" which is synonymous
with "all,nohrtime,nomtab,noxdrtrace".
Changed the misleading inverted logic of certain debug_options:
1. "xdrtrace" is included in "all" because "all" (as the name implies),
should be *all* options, not just a subset. If you want the old behavior
of "all" then use "defaults" (all only adds "xdrtrace" which can be
chatty on some systems).
2. Certain debug options are hereby declared immutable: they may not be
changed by "amq -D" after Amd starts, because it doesn't make much sense
to change them after Amd starts, and it could really mess up Amd. These
immutable flags are currently "daemon," "fork," "amq," and "mtab."
3. the debug option "daemon" *will* cause Amd to daemonize. Before, it was
causing Amd NOT to daemonize. This was greatly confusing, especially
since the code, documentation, and comments often conflicted with each
other. If you don't want Amd to daemonize, which is useful for debugging
it, then use the debug option "nodaemon" -- it makes a lot more sense.
4. Similarly, the "fork" option *will* cause Hlfsd to fork. Use "nofork" if
you don't want Hlfsd to fork. This option is only applicable to Hlfsd.
5. Similarly, the "amq" option, which is now on by default, will cause Amd
to register itself with the RPC portmapper (for Amq), as is done
normally. If you don't want Amd to register with the portmapper, use
"noamq" -- this naming convention makes more sense. This was also
confusingly documented and coded in places.
Note: unfortunately, these changes to the "daemon," "fork," and "amq"
debug options may be incompatible with people's previous use of Amd.
Some of you may have to update your amd.conf slightly or your startup
options (if they're hard-coded in your amd startup script). Sorry, but
we have to fix those old problems sooner or later. However, if you never
set any debug_options, or you used to "all," then you won't be affected
by the change in meaning of these three flags.

** General notes about the autofs support in am-utils
- The autofs code in am-utils is gamma quality for Linux, beta quality for
Solaris 2.5+ and non-working for all the other systems.
- Link, lofs, ufs, nfs, nfsl, and auto mounts were tested and work properly;
the others should work, but were not tested.
* Caveats:
- [this applies to Solaris/IRIX 6/HP-UX/AIX] Amd acts as *both* automountd and
automount. There's no way to distinguish between the two. When amd starts,
it first registers itself as an autofs server (automountd's job), then
parses its own maps, and decides which autofs-type mounts to make
(automount's job). After the autofs mounts are made, amd listens for
requests from the kernel-based autofs, and acts upon them. Since there can
be only one autofs listener on a system, this means that automountd and amd
cannot run at the same time; nor can two amd's run at the same time if they
are both using autofs mounts.
- Linux support is available and fairly stable. Solaris 2.5+ support is
newer and less tested, but seems pretty stable as well. IRIX 6 and HP-UX
autofs support will probably be very easy once we get Solaris 2.5 to work,
as they use the same protocol and almost identical data structures. AIX
seems to be using the Solaris 2.5 protocol as well, but they don't provide
any headers or documentation so getting autofs to work will be tricky at best.
- Killing amd can become a problem if there are active mounts. Since mounts
are done "in place", we can't just unmount our mount points and go away. For
now, amd simply tells the kernel that it is dying; we need to think this
further. It would be nice to "take over" the old mountpoints, there is
support for this in Solaris (due to is RPC nature) and is easy to add to
the Linux kernel (an ioctl on the mountpoint).
- The Solaris 2.5 implementation of the autofs v1 protocol is NON-REENTRANT,
and ignoring this limitation results in a DEADLOCK between the kernel and
the daemon. This is a serious problem, although only for the lofs and link
mount types. In other words, suppose the daemon is trying a lofs/link mount
whose destination crosses another autofs mountpoint. If that mountpoint is
not yet mounted, it will trigger another autofs lookup which will deadlock
inside the kernel -- because the kernel is waiting for the previous request
to return. This is not even something specific to amd, Sun's own automountd
has the exact same problem. Ctrl-C breaks the deadlock, so it's not fatal,
but the lofs/link entry is in effect unusable.
- Solaris 2.8 (at least) doesn't like getting to get out-of-order replies to
mount requests, and ignores the late ones. It's only a minor annoyance (read
delay), because the RPC is retried by the kernel and it succeeds the second
time around.
* Solaris:
- Amd w/ autofs mounts will fight over the listener port with Sun's
automountd, so running both simultaneously is a really bad idea.
- Browsable_dirs is possible and implemented for Solaris 2.6+.
- Direct mounts are implemented and work correctly.
- Host maps are implemented and work correctly.
- On Solaris 2.6+, symlinks over autofs are inefficient. The kernel seems to
time them out immediately after receiving them, so each access to a
symlink causes a call to userspace. Needless to say, this negates the
whole point of using autofs. Automountd seems to always use lofs mounts
instead of symlinks, we do the same unless the admin requests
"autofs_use_lofs = no" in amd.conf.
- Solaris 2.5/2.5.1 do not support symlinks over autofs, so links are always
mounted as lofs mounts, subject to the limitation described in the caveats
section above.
- Restarting autofs mounts is possible, but not yet implemented.
* Linux:
- Amd should work fine even when the Linux automounter is running, the
mechanism being used prevents any kind of (evil) interaction between them.
- Browsing is not available if autofs support is used, due to limitations in
the kernel<->daemon protocol used by Linux 2.2 and 2.4. Only already-mounted
nodes will appear in the autofs directory, and this is implemented entirely
in the kernel.
- Host maps are supported with all autofs versions.
- Direct maps cannot be supported since there is no kernel support for them;
we might be able to get something eventually, but don't hold your breath.
If anything, we may do it using a regular NFS mountpoint and bind-mount on
top of it.
- Inherit doesn't make much sense because we can't restart a hung autofs
mount point, due to kernel limitations. This needs to be fixed in the
Linux kernel; it's not particularly difficult, and we might provide a
patch at some point.
- Link (and lofs) mounts will use the new bind-mount support in Linux
2.4+. No more symlinks! And /bin/pwd works great too.
- Auto maps are actually mounted as a separate autofs filesystem. Since each
autofs filesystem consumes 2 file descriptors, and amd has at most 1024
file descriptors available, there can be at most 512 of them mounted at
the same time. Because of this, extensive use of auto maps is discouraged
when using autofs on Linux.
* amd.conf requirements:
To tell amd to use an autofs-style mount point and mounts for a map, add
mount_type = autofs
either to the global section, or to the sections of the individual maps you
selected. Mixing autofs and normal amd mount points in the same amd.conf
file *does* work.
* Map changes:
No changes are necessary. If a map is marked as autofs in amd.conf, mounts
are done "in place" and the "fs" parameter is ignored most of the time.
* Todo:
We are looking for volunteers to improve the autofs code!
(1) These fixes are needed:
- sublinks are broken
- when the mount type is 'link', transparently translate it into a loopback
file system mount (lofs), that would mount in place, rather than supply a
symlink, at least on systems whose autofs doesn't support symlinks. Linux
does support symlinks, Solaris 2.6+ does too, but Solaris 2.5/2.5.1 doesn't
and neither does IRIX 6. Moreover, Sun's automountd always uses lofs for
link mounts, even on 2.6+, because symlinks are not cached in the kernel and
thus are not particularly efficient. [done]
- complain if certain incompatible options (autofs and ...) are used. Direct
maps on Linux is one such case of incompatible options. Browsable_dirs on
Linux is another such case.
- if amd is killed or dies, the autofs mounts will remain intact as required
(your system is _not_ hung, yay!). However, if you restart amd, it will not
correctly 'restart' the autofs mounts as the Sun automounter does. Rather,
it might cause another mount to happen, which leaves your /etc/mnttab
cluttered with older mounts entries which cannot be unmounted. It might also
just pretend everything is ok, when in fact it isn't.
(2) Code expansion:
- [Solaris only] implement the sockets version of amu_get_autofs_address()
and create_autofs_service(), in conf/transp/transp_sockets.c. Not sure if
it's necessary, Solaris it still biased towards TLI/STREAMS in
userspace. [mostly done, untested, might be used on AIX 5.x+ and IRIX 6]
- Implement the restarting of autofs mount points. This is already doable on
Solaris; on Linux, the kernel needs to be patched to allow it.
(3) Testing and porting to other systems:
- nothing has been tested on IRIX 6, which reportedly has a similarly
functioning autofs to Solaris 2.5. The code compiles, but has not been run
yet and is most likely broken.
- support for Linux autofs is stable, we need testers!
- support for Solaris 2.6+ is pretty stable, so we need testers for it, too!
- we did not test any version of Solaris on x86. It will probably work, but
you have been warned. Testers are welcome.

The stock amd didn't work for us in Mac OS X 10.3.
Here's how we installed am-utils-6.1-20031025:
./configure --prefix=/usr
make
make install
Create /System/Library/StartupItems/AMD with the files:
AMD
Resources/ -- copy from other directories in ..

Then, make sure that AMDSERVER=-YES- is added to /etc/hostconfig.

Sun-style Automounter Syntax Support in Amd
Last updated: October 10, 2005
* Summary
The goal of this effort is to provide a drop in replacement for the Sun
automounter. This is implemented in two ways. (1) A new parser built into
Amd. (2) a standalone sun2amd Unix filter tool that can convert Sun-style
maps to Amd maps.
Support for Sun-style maps in Amd (including this document) is a
work-in-progress. This feature as a whole has not been throughly tested and
is "alpha" quality as of the date posted at the top of this document.
* Status
Currently sun2amd supports most of the basic syntax features of Sun maps.
However, support for Sun auto.master maps does not yet exists at any level.
Below is a list of supported and not-yet supported features.
1. Supported Sun map features:
- Simple map entry format: <key> [mount_options] location ...
locations take the form of host:pathname
- Map Key Substitution: <key> <hostname>:/tmp/&
the & expands to <key>
- Wildcard Key: * <hostname>:/tmp
This is is a catch-all entry.
- Variable Substitution:
$ARCH, $CPU, $HOST, $OSNAME, $OSREL, $OSVERS, $NATISA
- Multiple Mount format:
<key> [mount_options] [mountpoint] [mount-options locations...]...
ex.
pluto -ro /tmp1 host1:/tmp1 /tmp2 host2:/tmp2
- HSFS file-system (cdrom): <key> -fstype=hsfs,ro :/dev/cdrom
2. Not-yet supported Sun map features:
- Replicated File Systems: <hostname>,<hostname>...:<pathname>
This is a feature of Solaris that allows a user to specify a
set of hosts to appear as one in a map entry. When a host
does not respond the kernel will switch to an alternate
server. Amd will supports the syntax for replicated file
systems by creating multiple hosts, however, Amd will not
perform any kind of fail over.
- CacheFS (although Amd supports type:=cachefs, sun2amd doesn't yet parse
it).
- AutoFS (although Amd supports Autofs mounts and type:=auto, sun2amd
may not parse it fully).
- Included maps: +<map_name>
This will include the contents of a map into another map.
- Sun master maps: auto.master
Amd still relies and amd.conf. Any feature in auto.master
must be duplicated using Amd equivalent features in amd.conf.
- /net mount point:
The automounter is suppose to dynamically create map entries
under this mount point corresponding to NFS server(s) exported
file systems. While this isn't parser by sun2amd, Amd does support
host maps (type:=host).
- Federated Naming Service (FNS) (-xfn):
A naming server that wraps a number of other naming service
under one interface.
- "-null" map option: A way to cancel maps in the auto.master file.
- nsswitch.conf:
This file provides a way to specify what lookup service to use
for a number of systems including Sun's automounter. In amd
lookup services for map files are define in the amd.conf file.
* Setup
To enable Sun-style maps in Amd, set "sun_map_syntax = yes" in your amd.conf
file. When this flag is set in [global], all maps read by Amd are assumed
to be Sun style maps. You can set this on a per map basis, thus mixing
Sun-style and Amd-style maps. For more information about amd.conf please
see the Amd documentation.
Example:
# file: amd.conf
################
[ global ]
sun_map_syntax = yes
[ /home ]
map_name = /etc/amd.sun_map
map_type = file
* sun2amd command line utility
In addition to build-in Amd support there also exists the sun2amd command
line utility that converts Sun maps to Amd maps. This can be useful in
migrating one or more Sun maps to the Amd syntax in one step.
Example usage:
$ sun2amd -i sun_map -o amd_map
This line tells sun2amd to read the file sun_map and redirect its output to
a file called amd_map. By default sun2amd reads from stdin and writes to
stdout (i.e., traditional Unix filter).
* FAQ
Q1: I know "/net" is not supported, but how can I achieve the same
functionality with Amd?
A1: In short, you must create the '/net' entry as a Amd entry of type host
by hand. Below is an example of how to do this. See the Amd
documentation on type autofs for more information.
Example:
# file: amd.conf
################
[ /net ]
map_name = /etc/amd.net
# file: /etc/amd.net
###############
/defaults fs:=${autodir}/${rhost}/root/${rfs}
* rhost:=${key};type:=host;rfs:=/
(more FAQ entries to come...)

.SH NAME
sun2amd \- converts Sun automount maps to Amd maps
.SH SYNOPSIS
.B sun2amd
[-hH] [-i infile] [-o outfile]
.SH DESCRIPTION
.B sun2amd
is used to convert Sun style automount maps to Amd style automount
maps. By default
.B sun2amd
reads from stdin and writes to stdout.
.SH OPTIONS
.TP
.B -h
Help
.TP
.B -i
Read Sun map information from specified file.
.TP
.B -o
Write Amd map information to specified file.
.SH EXAMPLE
To convert a Sun automount file called auto_foo to an Amd file called
auto.amd type:
.B sun2amd
-i auto_foo -o auto.amd
.SH BUGS
* Can not convert master maps yet.
* NFS is the only automount type currently supported.
