systems are fully "ready to go".
'FILESYSTEMS' states: "This is a dummy dependency, for services which
require file systems to be mounted before starting." However, we have
'var' which is was run after 'FILESYSTEMS' and can mount /var if it
already isn't mounted. Furthermore, several scripts cannot use /var
until 'cleanvar' has done its thing. Thus "FILESYSTEMS" hasn't really
meant all critical file systems are fully usable.
like, determines the path to a pid file as it is specified in a conf file.
Use the new feature for rc.d/named and rc.d/devd, the 2 services in the
base that list their pid files in their conf files.
Remove the now-obsolete named_pidfile, and warn users if they have it set.
named_chrootdir IS set, named-checkconf fails because it
cannot find the conf file. Fix this by making checkconf a
variable that includes "-t $named_chrootdir" as needed.
Notice of the bug and suggested direction for the fix from [1].
Using required_files for named.conf is overkill ever since
I added the named-checkconf call, so rather than update the
logic to handle the case described above, remove it. This
also handles the case where named_chroot_autoupdate IS set
but the symlink doesn't exist yet.

would be "/etc/namedb" in a number of places. Since the user may make
a different choice, introduce a new internal variable, named_confdir
that is generated relative to the location of $named_conf.
While this will work for some things (especially a highly customized
build from ISC source) there are still a number of places where
/etc/namedb is assumed that it is not easily virtualized (E.g., mtree).
If you deviate from the defaults you'd better know what you're doing. :)
command in the rc.d script if we have a corresponding ${name}_program
entry, which we do for named.
Rename named_precmd to named_prestart to make it more clear and match
convention.
Move the command_args definition related to -u up into _prestart().
It (and the associated $named_uid value) are only used there, and
unlike required_* and pidfile don't need to be used until this stage.
Fix a silly bug that would only have affected people who were using
the new named_wait or named_auto_forward features, AND had set up an
rndc.conf file instead of using the automatically generated rndc.key.
For named_conf:
Add "-c $named_conf" to command_args if it's not set to the
default. If it is set to the default and we're using the base
BIND it's not necessary. If we're using BIND from the ports
the user is likely to have included it in _flags (due to long
necessity for doing so) so don't duplicate that if it's set.
Add $named_conf to required_files

2. New feature: option to create a forwarder configuration file based on

Off by default.
3. Add named-checkconf into the startup routine. This will prevent named

so.

so that when using named from the ports (or elsewhere) the proper rndc*
commands will be run.
2. Rework the stop routine using ideas from brooks and delphij.
Specifically I am duplicating a lot of code from rc.subr's stop routine
so that this one will behave more like the one in rc.subr, but use rndc
to kill the daemon (or regular kill if that fails). This also avoids
the problems related to using killall if rndc fails, which is bad if
you're running more than one named on the same box.
3. Take a concept from gshapiro and allow the rndc.key file to be
owned by root OR the named_uid user.

1. Remove a now-spurious NetBSD CVS Id, as we are no longer synching work
2. Remove a now-spurious BEFORE, since ntpdate now REQUIRE's named
3. Replace the call to set rcvar with what that function would output,
and generally reduce indirection ($name -> named) since it's highly
unlikely the name of the named process or service will change any time soon.
4. Resort the order the variables at the top of the file to a more
traditional format, and remove a spurious required_dirs from the top, as it
works better after load_rc_config.
5. We do not want the default reload method with named, so define a simple
but appropriate substitute using rndc. If I were writing this script for
the first time I would not include this at all, since it's preferable to
control a running daemon with rndc to start with, but given that this is
already here, let's do it right. I hope that future generations will
however resist the tempation to add reconfig to extra_commands.
6. By the same token, we want to use rndc to shut down named, but given
that by defining a stop function we lose the "find the process by its
pid file in an emergency" goodness of rc.subr, try to do something useful
in the event that rndc is not available, and keep the user informed.
7. Replace some "test -f" with "test -r" to handle the unlikely event
that the relevant file exists, but is unreadable.
8. Twiddle whitespace in a few areas, remove a spurious blank line,
a bogus double space, and try to do better indenting.
9. Improve generation of the rndc.key file significantly
a. If for some reason a user has an rndc.conf file, assume that they
did that on purpose, and hence know what they are doing, so leave them alone.
b. Introduce a named_uid configuration variable so that the user which owns
the rndc.key file and the user named runs as always match, and is more
easily configurable. This should dramatically reduce problems with rndc.
c. Also test that the rndc.key file size is greater than zero, rather than
simply that the file exists. I have seen at least one user report this exact
problem, and although neither of us is sure where the empty file came from,
the fix is simple, so include it.
d. Rather than try to create an rndc.key file in both /etc/namedb and the
chroot'ed /etc/namedb, assume that they are be the same (which they should
be), and only create the file in the chroot'ed version of the directory.
This partially addresses the problem described in conf/73929, but I have
not yet finished thinking about the PREFIX issue that PR also raises.
As a result of introducing the named_uid knob, the default named_flags
are now empty.
Update defaults/rc.conf and rc.conf(5) to reflect these changes.
/etc/defaults/rc.conf will provide foo_program, too.
By specifying "command" we explicitly say that we're
going to rely on rc.subr(8) default methods, and
rc.subr(8) will take advantage of this soon.
The majority of our rc.d scripts already set "command"
if appropriate, so fix just the non-compliant handful.
because new devfs entries can show up later and one can access such entires
from inside named chroot.
In rc.d scripts we can use devfs_domount() function with devfsrules_hide_all
policy and unhide 'null' and 'random' manually.
Without this flag, if the symlink existed already a new symlink would
be created in the source directory. While harmless if the two symlinks
were the same, it nonetheless caused pointless confusion.
The pathological case is that when there is an existing /etc/namedb
symlink, but named_chrootdir in rc.conf pointed to a different
directory, it was the symlink in /var/named that was getting
updated, not the one in /etc. This led to some difficult to diagnose
problems for users.
by default when named is enabled. Also, improve our default directory
layout by creating /var/named/etc/namedb/{master|slave} directories,
and use the former for the generated localhost* files.
Rather than using pax to copy device entries, mount devfs in the
chroot directory.
There may be some corner cases where things need to be adjusted,
but overall this structure has been well tested on a production
network, and should serve the needs of the vast majority of users.
UPDATING has instructions on how to do the conversion for those
with existing configurations.
chrooted the pid symlink code should not fire. Also, remove the quotes
around the chroot variable in the rndc-confgen invocation so that if
not chrooted the command will still succeed.

1. Making the pid symlink now has to happen after named starts, otherwise
it can generate a fatal error.
2. named-xfer is not part of the BIND 9 world.
3. BIND 9 needs a /dev/random in the chroot directory if chrooted.
4. Only the pid file is symlinked now, the ndc socket is BIND 8 only.
5. Create an rndc.key file for the user if one does not exist.
This (generally) allows a BIND 8 config file to be used in a BIND 9
world with little or no modification.
thing, but we're ready to move on.
2. Remove the -g default argument in named_flags. It doesn't actually do
what most users think it does, and what most users want it to do is already
accomplished with a proper default group for the bind user, which we have.
Also, the -g knob does something entirely different in BIND 9, which leads
to a lot of needless confusion/aggravation.
3. In the rc.d script, don't bogusly override $command, or $rc_flags. Both
are adequately handled in rc.conf[.local].
4. DO properly override $rc_flags if user has named_chrootdir set.
This may need to be revisited, but should be ok for now.
5. Protect all chrootdir-related bits under that variable, instead of
named_rcng.
There is more work to be done here, especially in the area of BIND 9
compatibility, but this is a start at least.
