NAME

image-minimizer − Utility script to remove files and packages **
Authors**

image−minimizer is a script used as an interpreter for kickstart %post sections. It is used to remove rpm packages and individual files from the system that Anaconda has just installed.

It processes a list of commands that tell it which files or rpms to remove, and which to keep.

IMAGE-MINIMIZER CMDLINE ARGUMENTS

usage: image−minimizer [−h] [−i STRING] [−−dryrun] [−v] STRING

Optional arguments

−h, −−help

show this help message and exit

**−i **STRING, **−−installroot **STRING

Root path to prepend to all file patterns and installation root for RPM operations. Defaults to INSTALL_ROOT or /mnt/sysimage/

−−dryrun

If set, no filesystem changes are made.

−v, −−verbose

Display every action as it is performed.

Positional arguments


	STRING		Filename to process

NOTES

You cannot pass any arguments to image−minimizer when using it from the kickstart %post.

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 lorax in the %package section. You can use image−minimizer to remove lorax from the install.

If you are using this with livemedia−creator it can be installed on the host system so that lorax isn’t needed in the %package list, and it doesn’t need to be removed.

COMMANDS

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 *, ?, and [] character ranges. globbing is implemented using the python glob module.


	•		drop <PATTERN> This will remove files from the installation.
	•		keep <PATTERN> This will keep files, and should follow any drop commands including globs.
	•		droprpm <PATTERN> Remove matching rpm packages. Dependencies are not remove, just individual packages matching the glob.
	•		keeprpm <PATTERN> Do not remove matching rpm packages, it should follow any droprpm commands that include globs.

EXAMPLE

Example Anaconda %post usage:

%post −−interpreter=image−minimizer −−nochroot

drop /lib/modules/*/kernel/fs
keep /lib/modules/*/kernel/fs/ext*
keep /lib/modules/*/kernel/fs/mbcache*
keep /lib/modules/*/kernel/fs/squashfs

droprpm make
droprpm mtools
droprpm mysql−libs
droprpm perl
droprpm perl−Pod−*
droprpm syslinux
keeprpm perl−Pod−Simple

# Not needed after image−minimizer is done
droprpm lorax

%end
