.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to add and delete instances of depoted packages in
|
|
.Ar stowdir
|
|
in a
|
|
.Ar view
|
|
in the
|
|
.Ar viewbase
|
|
directory.
|
|
.Sh WARNING
|
|
.Bf -emphasis
|
|
Since the
|
|
.Nm
|
|
command may execute scripts or programs provided by a package file,
|
|
your system may be susceptible to
|
|
.Dq 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 database directory
|
|
.Pa ( /usr/pkg/packages/\*[Lt]pkg-name\*[Gt]/ ) .
|
|
Pay particular attention to any
|
|
.Pa +INSTALL
|
|
or
|
|
.Pa +DEINSTALL
|
|
files, and inspect the
|
|
.Pa +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 installed package control files.

as the directory in which the depoted packages can be found.

is taken from the value of the environment variable
|
|
.Ev DEPOTBASE
|
|
if it's set, otherwise the default
|
|
.Ar stowdir
|
