.Sh DESCRIPTION
|
||||
The
|
||||
.B pkg_add
|
||||
.Nm
|
||||
command is used to extract packages that have been previously created
|
||||
with the
|
||||
.B pkg_create
|
||||
.Xr pkg_create 8
|
||||
command.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
The following command line options are supported.

.Sh WARNING
|
||||
.Bf -emphasis
|
||||
Since the
|
||||
.Nm
|
||||
command may execute scripts or programs contained within a package file,
|
||||
your system may be susceptible to ``trojan horses'' or other subtle
|
||||
attacks from miscreants who create dangerous package files.
|
||||
.Pp
|
||||
You are advised to verify the competence and identity of those who
|
||||
provide installable package files. For extra protection, use the
|
||||
.Fl M
|
||||
flag to extract the package file, and inspect its contents and scripts
|
||||
to insure it poses no danger to your system's integrity. Pay particular
|
||||
attention to any +INSTALL, +DEINSTALL, +REQUIRE or +MTREE_DIRS files,
|
||||
and inspect the +CONTENTS file for
|
||||
.Cm @cwd ,
|
||||
.Cm @mode
|
||||
(check for setuid),
|
||||
.Cm @dirrm ,
|
||||
.Cm @exec ,
|
||||
and
|
||||
.Cm @unexec
|
||||
directives, and/or use the
|
||||
.Xr pkg_info 1
|
||||
command to examine the package file.

.Sh OPTIONS

|

.B \-R
|

|

.It Fl R
|

Do not record the installation of a package. This means
|

that you cannot deinstall it later, so only use this option if
|

you know what you are doing!

installed or the requirements script fails.

.It Fl p Ar prefix
|
||||
Sets
|
||||
.I prefix
|
||||
.Ar prefix
|
||||
as the directory in which to extract files from a package.
|
||||
If a package has set its default directory, it will be overridden
|
||||
by this flag. Note that only the first directory default will
|
||||
be replaced, since
|
||||
.B pkg_add
|
||||
.Nm
|
||||
has no way of knowing which directory settings are relative and
|
||||
which are absolute. It is rare, in any case, that more than one
|
||||
directory transition is made, but when such is the case then you
|
||||
may wish to look into the use of
|
||||
.B MASTER
|
||||
.Cm MASTER
|
||||
and
|
||||
.B SLAVE
|
||||
mode (see
|
||||
.B \-M
|
||||
.Cm SLAVE
|

mode (see the
|
||||
.Fl M
|

and
|

.B \-S

options).

|

.TP
|

.BI "\-t\ " template
|
||||
.Em "Optional."
|
||||
.It Fl t Ar template
|
||||
Use
|
||||
.I template
|
||||
as the input to mktemp(3). By default, this is the string
|
||||
.B /tmp/instmp.XXXXXX
|
||||
, but it may be necessary to override it in the situation where
|
||||
.Ar template
|
||||
as the input to
|
||||
.Xr mktemp 3
|
||||
when creating a ``staging area.''
|
||||
By default, this is the string
|
||||
.Pa /tmp/instmp.XXXXXX ,
|
||||
but it may be necessary to override it in the situation where
|
||||
space in your
|
||||
.B /tmp
|
||||
.Pa /tmp
|
||||
directory is limited. Be sure to leave some number of `X' characters
|

for mktemp(3) to fill in with a unique ID.

for

|

.Pp
|
||||
You can get a performance boost by setting the staging area
|
||||
.Ar template
|
||||
to reside on the same disk partition as target directories for package
|
||||
file installation; often this is
|
||||
.Pa /usr .

.B MASTER
|

.Cm MASTER
|
||||
mode. This is a very specialized mode for running
|
||||
.B pkg_add
|
||||
.Nm
|
||||
and is meant to be run in conjunction with
|
||||
.B SLAVE
|
||||
.Cm SLAVE
|
||||
mode. When run in this mode,
|
||||
.B pkg_add
|
||||
.Nm
|
||||
does no work beyond extracting the package into a temporary staging
|
||||
area (see
|
||||
.B \-t
|
||||
area (see the
|
||||
.Fl t
|
||||
option), reading in the packing list, and then dumping it (prefaced by
|
||||
the current staging area) to stdout where it may be filtered by a
|
||||
program such as
|
||||
.B sed(1).
|
||||
.Xr sed 1 .
|
||||
When used in conjunction with
|
||||
.B SLAVE
|
||||
.Cm SLAVE
|
||||
mode, it allows you to make radical changes to the package structure
|
||||
before acting on its contents.

.Cm MASTER

|

.B pkg_add
|

.Nm
|

expects the release contents to be already extracted and waiting
|
||||
in the staging area, the location of which is read as a string
|

from stdin. The complete packing list is also read from stdin,
|
||||
and the contents then acted on as normal.

.Nm

is fairly simple. It simply extracts the requested packages into
|

a "staging area" directory and then performs the following steps:
|
||||
.PP
|
||||
a ``staging area'' directory and then performs the following steps:
|
||||
.Bl -enum -indent indent
|
||||
.It
|
||||
It checks whether the package is already recorded as installed; if so,
|
||||
the installation terminates.
|
||||
.It
|
||||
It checks whether all the package dependencies (from
|
||||
.Cm @pkgdep
|
||||
directives, see
|
||||
.Xr pkg_create 8 )
|
||||
are met; if not, the missing dependencies are printed and the
|
||||
installation terminates.
|
||||
.It
|
||||
If the package contains a
|
||||
.B require
|
||||
.Ar require
|
||||
file (see
|
||||
.B pkg_create
|
||||
), then this is executed first with the flags
|
||||
.PP
|
||||
.B <script>
|
||||
.I pkg-name INSTALL
|
||||
.PP
|
||||
to see whether or not installation should
|
||||
continue (a non-zero exit status means no).
|
||||
.PP
|
||||
If an
|
||||
.B install
|
||||
script exists for the package, it is then executed as follows:
|
||||
.PP
|
||||
First, before installing files in the data set, the
|
||||
.B install
|
||||
script is called with the flags
|
||||
.PP
|
||||
.B <script>
|
||||
.I pkg-name PRE-INSTALL
|
||||
.PP
|
||||
Where
|
||||
.I pkg-name
|

.Xr pkg_create 8 ),
|

then this is executed first as
|
||||
.Bd -filled -offset indent -compact
|
||||
.Cm require
|
||||
.Ar <pkg-name>
|
||||
.Ar INSTALL
|
||||
.Ed
|
||||
where
|
||||
.Ar <pkg-name>
|
||||
is the name of the package in question and
|
||||
.I PRE-INSTALL
|
||||
is a keyword denoting that this is the "pre installation" pass.
|
||||
Using the packing list as a guide, files are then moved (or copied,
|
||||
as necessary) from the staging area into their new homes and the
|
||||
.B install
|
||||
script is then executed a second time with the flags
|
||||
.PP
|
||||
.B <script>
|
||||
.I pkg-name POST-INSTALL
|
||||
.PP
|
||||
This all allows you to write an
|
||||
.B install
|
||||
script that does "before and after" actions.
|
||||
.PP
|
||||
.Ar INSTALL
|
||||
is a keyword denoting that this is an installation requirements check.
|
||||
.It
|
||||
If an
|
||||
.Ar install
|
||||
script exists for the package, it is then executed as
|
||||
.Bd -filled -offset indent -compact
|
||||
.Cm install
|
||||
.Ar <pkg-name>
|
||||
.Ar PRE-INSTALL
|
||||
.Ed
|
||||
where
|
||||
.Ar <pkg-name>
|
||||
is the name of the package in question and
|
||||
.Ar PRE-INSTALL
|
||||
is a keyword denoting that this is the preinstallation phase.
|
||||
.It
|
||||
Using the packing list (the
|
||||
.Pa +CONTENTS
|
||||
file) as a guide, files are then moved (or copied, as necessary) from
|
||||
the staging area into their final locations.
|
||||
.It
|
||||
If the package contains an
|
||||
.Ar mtreefile
|
||||
file (see the
|
||||
.Fl m
|
||||
option to
|
||||
.Xr pkg_create 8 ),
|
||||
then mtree is invoked as
|
||||
.Bd -filled -offset indent -compact
|

.Cm mtree
|

.Fl u
|

.Fl f
|
||||
.Ar mtreefile
|
||||
.Fl d
|
||||
.Fl e
|
||||
.Fl p
|
||||
.Pa prefix
|
||||
.Ed
|
||||
where
|
||||
.Pa prefix
|
||||
is either the prefix specified with the
|
||||
.Fl p
|
||||
flag or, if no
|
||||
.Fl p
|
||||
flag was specified, the name of the first directory named by a
|
||||
.Cm @cwd
|
||||
directive within this package.
|
||||
.It
|
||||
If an
|
||||
.Ar install
|
||||
script exists for the package, it is then executed as
|
||||
.Bd -filled -offset indent -compact
|
||||
.Cm <script>
|
||||
.Ar <pkg-name>
|
||||
.Ar POST-INSTALL
|
||||
.Ed
|
||||
This all allows you to write a single
|
||||
.Ar install
|
||||
script that does both ``before and after'' actions.
|
||||
.It
|
||||
After installation is complete, a copy of the packing list,
|
||||
.Ar deinstall
|
||||
script, description, and display files are copied into
|
||||
.Pa /var/db/pkg/<pkg-name>
|
||||
for subsequent possible use by
|
||||
.Xr pkg_delete 8 .
|
||||
Any package dependencies are recorded in the other packages'
|
||||
.Pa /var/db/pkg/<other-pkg>/+REQUIRED_BY
|
||||
file.
|

.It
|
||||
Finally, the staging area is deleted and the program terminates.
|

.Pp
|

All the scripts are called with the environment variable
|

.B PKG_PREFIX
|

.Ev PKG_PREFIX
|
||||
set to the installation prefix (see the
|
||||
.B -p
|
||||
.Fl p
|
||||
option above). This allows a package author to write a script
|
||||
that reliably performs some action on the directory where the package
|
||||
is installed, even if the user might change it by
|
||||
.B -p
|
||||
when
|
||||
.B pkg_add
|

is run.
|

.PP
|

After installation is complete, a copy of the packing list, in addition
|
||||
to any
|

.B deinstall
|

for subsequent possible use by

|
||||
The ``packing list'' format (see
|
||||
.Fl f )
|
||||
is fairly simple, being
|
||||
nothing more than a single column of filenames to include in the
|
||||
package. However, since absolute pathnames are generally a bad idea
|
||||
for a package that could be installed potentially anywhere, there is
|
||||
@ -155,126 +185,178 @@ another method of specifying where things are supposed to go
|
||||
and, optionally, what ownership and mode information they should be
|
||||
installed with. This is done by imbeding specialized command sequences
|
||||
in the packing list. Briefly described, these sequences are:
|
||||
.TP
|
||||
.BI "@cwd\ " directory
|
||||
.Bl -tag -width indent -compact
|
||||
.It Cm @cwd Ar directory
|
||||
Sets the internal directory pointer to point to

.I directory.

||||
All subsequent filenames will be assumed relative to this directory.

||||
Note:
|
||||
.BI @cd

||||
.Cm @cd
|

is also an alias for this command.

.It Cm @srcdir Ar directory
|
||||
Sets the internal directory pointer for _creation only_ to

.Ar directory .
|
||||
That is to say that it overrides

for package creation but not extraction.

.It Cm @exec Ar command

Execute

as part of the unpacking process. If
|
||||
.I command
|
||||
.Ar command
|
||||
contains a any of the following sequences somewhere in it, they will
|

be expanded inline. For the following examples, assume that

is set to

in the example case

|

Expands to the "basename" of the fully qualified filename, that

.Pa /usr/local .

.It Cm "%B"
|

Expands to the ``basename'' of the fully qualified filename, that

is the current directory prefix, plus the last filespec, minus

Expands to the "filename" part of the fully qualified name, or

Expands to the ``filename'' part of the fully qualified name, or

the package's table of contents (and hence not automatically

.It Cm @ignore
|

Used internally to tell extraction to ignore the next file (don't

copy it anywhere), as it's used for some special purpose. Also useful

if you want to pack some specialized datafiles in with a distribution
|

for your install script (or something) and want to have the installer

ignore it.

.It Cm @ignore_inst
|
||||
Similar to
|
||||
.Cm @ignore ,
|
||||
but the ignoring of the next file is delayed one evaluation cycle. This
|
||||
makes it possible to use this directive in the
|
||||
.Ar packinglist
|
||||
file, so you can pack a
|
||||
specialized datafile in with a distribution for your install script (or
|
||||
something) yet have the installer ignore it.
|
||||
.It Cm @name Ar name
|
||||
Sets the name of the package. This is mandatory and is usually
|
||||
put at the top. This name is potentially different than the name of
|
||||
the file it came in, and is used when keeping track of the package
|
||||
for later deinstallation. Note that
|
||||
.B pkg_create
|

.Nm
|

will derive this field from the package name and add it automatically

if none is given.

|
||||
Since the

.Nm
|

command may execute scripts or programs provided by a package file,
|
||||
your system may be susceptible to ``trojan horses'' or other subtle
|
||||
attacks from miscreants who create dangerous package files.
|
||||
.Pp
|
||||
You are advised to verify the competence and identity of those who
|
||||
provide installable package files. For extra protection, examine all
|
||||
the package control files in the package record directory (
|
||||
.Pa /var/db/pkg/<pkg-name>/ ).
|
||||
Pay particular
|
||||
attention to any +INSTALL, +DEINSTALL, +REQUIRE or +MTREE_DIRS files,
|

.Nm
|

does pretty much what it says. It examines installed package records in
|
||||
.Pa /var/db/pkg/<pkg-name> ,
|
||||
deletes the package contents, and finally removes the package records.
|
||||
.Pp
|
||||
If a package is required by other installed packages,
|
||||
.Nm
|
||||
will list those dependent packages and refuse to delete the package
|
||||
(unless the
|
||||
.Fl f
|
||||
option is given).
|
||||
.Pp
|
||||
If the package contains a
|
||||
.B require
|
||||
.Ar require
|
||||
file (see
|
||||
.B pkg_create
|
||||
), then this is executed first with the flags
|
||||
.PP
|
||||
.B <script>
|
||||
.I pkg-name DEINSTALL
|
||||
.PP
|
||||
to see whether or not de-installation should continue (a non-zero exit
|
||||
status means no).
|
||||
.PP
|
||||
.Xr pkg_create 8 ),
|
||||
then this is executed first as
|
||||
.Bd -filled -offset indent -compact
|
||||
.Cm require
|
||||
.Ar <pkg-name>
|
||||
.Ar DEINSTALL
|
||||
.Ed
|
||||
(where
|
||||
.Ar pkg-name
|
||||
is the name of the package in question and
|
||||
.I DEINSTALL
|
||||
is a keyword denoting that this is a deinstallation)
|
||||
to see whether or not deinstallation should continue. A non-zero exit
|
||||
status means no, unless the
|
||||
.Fl f
|
||||
option is specified.
|
||||
.Pp
|
||||
If a
|
||||
.B de-install
|
||||
.Cm deinstall
|
||||
script exists for the package, it is executed before any files are removed.
|
||||
It is this script's responsibility to clean up any additional messy details
|
||||
around the package's installation, since all
|
||||
.B pkg_delete
|
||||
.Nm
|
||||
knows how to do is delete the files created in the original distribution.
|
||||
The
|
||||
.B de-install
|
||||
script is called with the flags
|
||||
.PP
|
||||
.B <script>
|
||||
.I pkg-name DEINSTALL
|
||||
.PP
|
||||
Where
|
||||
.I pkg-name
|
||||
is the name of the package in question and
|
||||
.I DEINSTALL
|
||||
is a keyword denoting that this is a deinstallation. Passing the keyword
|
||||
.Nm deinstall
|
||||
script is called as:
|
||||
.Bd -filled -offset indent -compact
|
||||
.Cm deinstall
|
||||
.Ar <pkg-name>
|
||||
.Ar DEINSTALL
|
||||
.Ed
|
||||
Passing the keyword
|
||||
.Ar DEINSTALL
|
||||
lets you potentially write only one program/script that handles all
|
||||
aspects of installation and deletion.
|
||||
.PP
|
||||
.Pp
|
||||
All scripts are called with the environment variable
|
||||
.B PKG_PREFIX
|
||||
.Ev PKG_PREFIX
|
||||
set to the installation prefix (see the
|
||||
.B -p
|
||||
.Fl p
|
||||
option above). This allows a package author to write a script
|
||||
that reliably performs some action on the directory where the package
|
||||
is installed, even if the user might have changed it by
|
||||
.B -p
|
||||
when
|
||||
.B pkg_add
|
||||
is installed, even if the user might have changed it by specifying the
|
||||
.Fl p
|
||||
option when running
|
||||
.Nm
|
||||
or
|
||||
.B pkg_delete
|
||||
is run.
