\fIimage\-minimizer\fP is a script used as an interpreter for kickstart \fI%post\fP
sections. It is used to remove rpm packages and individual files from the
system that Anaconda has just installed.
.sp
It processes a list of commands that tell it which files or rpms to remove, and
which to keep.

.SH NOTES
.sp
You cannot pass any arguments to \fIimage\-minimizer\fP when using it from the
kickstart \fI%post\fP\&.
.sp
When using this from a kickstart the image\-minimizer package needs to be available.
It is not included on the standard boot.iso, so you will need to include \fIlorax\fP in
the \fI%package\fP section. You can use \fIimage\-minimizer\fP to remove lorax from the install.
.sp
If you are using this with \fIlivemedia\-creator\fP it can be installed on the host
system so that \fIlorax\fP isn\(aqt needed in the \fI%package\fP list, and it doesn\(aqt need
to be removed.
.SH COMMANDS
.sp
Commands are listed one per line, followed by a space, and then by the
package, file, or glob.  The globs used are Unix style pathname patterns using
\fI*\fP, \fI?\fP, and \fI[]\fP character ranges. globbing is implemented using the python
glob module.
.INDENT 0.0
.IP \(bu 2
drop <PATTERN>
This will remove files from the installation.
.IP \(bu 2
keep <PATTERN>
This will keep files, and should follow any \fIdrop\fP commands including globs.
.IP \(bu 2
droprpm <PATTERN>
Remove matching rpm packages. Dependencies are not remove, just individual
packages matching the glob.
.IP \(bu 2
keeprpm <PATTERN>
Do not remove matching rpm packages, it should follow any \fIdroprpm\fP commands
that include globs.
