.SH "TECHNICAL DETAILS"
|
||
|
|
.B
|
||
|
|
pkg_delete
|
||
|
|
does pretty much what it says. It looks for a package in /var/db/pkg
|
||
|
|
and sets about deleting the files that make up the package and, finally,
|
||
|
|
the record of the package itself.
|
||
|
|
.PP
|
||
|
|
If the package contains a
|
||
|
|
.B require
|
||
|
|
file (see
|
||
|
|
.B pkg_create
|
||
|
|
), then this is executed first with the flag
|
||
|
|
.B DEINSTALL
|
||
|
|
to see whether or not de-installation should continue (a non-zero exit
|
||
|
|
status means no).
|
||
|
|
.PP
|
||
|
|
If a
|
||
|
|
.B de-install
|
||
|
|
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
|
||
|
|
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
|
||
|
|
lets you potentially write only one program/script that handles all
|
||
|
|
aspects of installation and deletion.
