.Sh NAME
|
|
.Nm pkg_add
|
|
.Nd a utility for installing software package distributions.
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl vInfRMS
|
|
.Op Fl t Ar template
|
|
.Op Fl p Ar prefix
|
|
.Ar pkg-name [pkg-name ...]
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to extract packages that have been previously created
|
|
with the
|
|
.Xr pkg_create 1
|
|
command.
|
|
|
|
.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.
|
|
.Ef
|
|
|
|
.Sh OPTIONS
|
|
The following command line arguments are supported.
|
|
.Bl -tag -width indent
|
|
.It Ar pkg-name [... pkg-name]
|
|
The named packages are installed. A package name of - will cause
|
|
.Nm
|
|
to read from stdin.
|
|
.It Fl v
|
|
Turns on verbose output.
|
|
.Em "Optional."
|
|
.It Fl I
|
|
If an installation script exists for a given package, do not execute it.
|
|
.Em "Optional."
|
|
.It Fl n
|
|
Don't actually install a package, just report the steps that
|
|
would be taken if it was.
|
|
.Em "Optional."
|
|
.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!
|
|
.Em "Optional."
|
|
.It Fl f
|
|
Forces installation to proceed even if prerequisite packages are not
|
|
installed or the requirements script fails.
|
|
.Em "Optional."
|
|
.It Fl p Ar prefix
|
|
Sets
|
|
.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
|
|
.Cm @cwd
|
|
directive will be replaced, since
|
|
.Nm
|
|
has no way of knowing which directory settings are relative and
|
|
which are absolute. It is rare in any case to see more than one
|
|
directory transition made, but when such does happen and you wish
|
|
to have control over *all* directory transitions, then you
|
|
may then wish to look into the use of
|
|
.Cm MASTER
|
|
and
|
|
.Cm SLAVE
|
|
modes (see the
|
|
.Fl M
|
|
and
|
|
.Fl S
|
|
options).
|
|
.Em "Optional."
|
|
.It Fl t Ar template
|
|
Use
|
|
.Ar template
|
|
as the input to
|
|
.Xr mktemp 3
|
|
when creating a ``staging area.''
|
|
By default, this is the string
|
|
.Pa /var/tmp/instmp.XXXXXX ,
|
|
but it may be necessary to override it in the situation where
|
|
space in your
|
|
.Pa /tmp
|
|
directory is limited. Be sure to leave some number of `X' characters
|
|
for
|
|
.Xr mktemp 3
|
|
to fill in with a unique ID.
|
|
.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 .
|
|
.Em "Optional."
|
|
.It Fl M
|
|
Run in
|
|
.Cm MASTER
|
|
mode. This is a very specialized mode for running
|
|
.Nm
|
|
and is meant to be run in conjunction with
|
|
.Cm SLAVE
|
|
mode. When run in this mode,
|
|
.Nm
|
|
does no work beyond extracting the package into a temporary staging
|
|
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
|
|
.Xr sed 1 .
|
|
When used in conjunction with
|
|
.Cm SLAVE
|
|
mode, it allows you to make radical changes to the package structure
|
|
before acting on its contents.
|
|
.It Fl S
|
|
Run in
|
|
.Cm SLAVE
|
|
mode. This is a very specialized mode for running
|
|
.Nm
|
|
and is meant to be run in conjunction with
|
|
.Cm MASTER
|
|
mode. When run in this mode,
|
|
.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.
|
|
.El
|
|
.Pp
|
|
One or more
|
|
.Ar pkg-name
|
|
arguments may be specified, each being either a file containing the
|
|
package (these usually ending with the ``.tgz'' suffix) or a
|
|
URL pointing at a file available on an ftp site. Thus you may
|
|
extract files directly from their anonymous ftp locations (e.g.
|
|
.Nm
|
|
ftp://ftp.freebsd.org/pub/FreeBSD/packages/shells/bash-1.14.4.tgz).
|
|
Note: If you wish to use
|
|
.Bf -emphasis
|
|
passive mode
|
|
.Ef
|
|
ftp in such transfers, set
|
|
the variable
|
|
.Bf -emphasis
|
|
FTP_PASSIVE_MODE
|
|
.Ef
|
|
to some value in your environment. Otherwise, the more standard
|
|
ACTIVE mode may be used. If
|
|
.Nm
|
|
consistently fails to fetch a package from a site known to work,
|
|
it may be because you have a firewall that demands the usage of
|
|
.Bf -emphasis
|
|
passive mode
|
|
.Ef
|
|
ftp.
|
|
.Sh TECHNICAL DETAILS
|
|
.Nm
|
|
is fairly simple. It extracts each packages' "packing list"
|
|
into a special staging directory in /tmp (or $PKG_TMPDIR if set), parses it,
|
|
then runs through the following sequence to fully extract the contents:
|
|
.Bl -enum -indent indent
|
|
.It
|
|
Check if the package is already recorded as installed. If so,
|
|
terminate installation.
|
|
.It
|
|
Scan all the package dependencies (from
|
|
.Cm @pkgdep
|
|
directives, see
|
|
.Xr pkg_create 1 )
|
|
and make sure each one is met. If not, print the missing dependencies and
|
|
terminate the installation.
|
|
.It
|
|
Search for any
|
|
.Cm @option
|
|
directives which control how the package is added to the system.
|
|
At the time of this writing, the only currently implemented option is
|
|
.Cm @option extract-in-place
|
|
which will cause the package to be extracted direcly into its
|
|
prefix directory without moving through a staging area in /tmp.
|
|
.It
|
|
If
|
|
.Cm @option extract-in-place
|
|
is enabled, the package is now extracted directly into its
|
|
final location, otherwise it is extracted into the staging area.
|
|
.It
|
|
If the package contains a
|
|
.Ar require
|
|
file (see
|
|
.Xr pkg_create 1 ),
|
|
then execute it with the following arguments:
|
|
.Bd -filled -offset indent -compact
|
|
.Ar pkg-name
|
|
.Ar INSTALL
|
|
.Ed
|
|
where
|
|
.Ar pkg-name
|
|
is the name of the package in question and the
|
|
.Ar INSTALL
|
|
keyword denotes this as an installation requirements check (useful if
|
|
you want to have one script serving multiple functions).
|
|
.It
|
|
If an
|
|
.Ar install
|
|
script exists for the package, it is then executed with the following arguments:
|
|
.Bd -filled -offset indent -compact
|
|
.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 this as the preinstallation phase.
|
|
.It
|
|
If
|
|
.Cm @option extract-in-place
|
|
is not used, then the packing list (this is the
|
|
.Pa +CONTENTS
|
|
file) is now used as a guide for moving (or copying, as necessary) files from
|
|
the staging area into their final locations.
|
|
.It
|
|
If the package contains an
|
|
.Ar mtreefile
|
|
file (see
|
|
.Xr pkg_create 1 ),
|
|
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 1 .
|
|
Any package dependencies are recorded in the other packages'
|
|
.Pa /var/db/pkg/<other-pkg>/+REQUIRED_BY
|
|
file
|
|
(if the environment variable PKG_DBDIR is set, this overrides the
|
|
.Pa /var/db/pkg/
|
|
path shown above).
|
|
.It
|
|
Finally, the staging area is deleted and the program terminates.
|
|
.El
|
|
.Pp
|
|
All the scripts are called with the environment variable
|
|
.Ev PKG_PREFIX
|
|
set to the installation prefix (see the
|
|
.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 with the
|
|
.Fl p
|
|
flag to
|
|
.Cm pkg_add .

|
|
Hard links between files in a distribution are only preserved if either
|
|
(1) the staging area is on the same file system as the target directory of
|
|
all the links to the file, or (2) all the links to the file are bracketed by
|
|
.Cm @cwd
|
|
directives in the contents file,
|
|
.Em and
|
|
and the link names are extracted with a single
|
|
.Cm tar
|
|
command (not split between
|
|
invocations due to exec argument-space limitations--this depends on the
|
|
value returned by
|
|
.Fn sysconf _SC_ARG_MAX ) .
