image-minimizer =============== :Authors: Brian C. Lane `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 This will remove files from the installation. * keep This will keep files, and should follow any `drop` commands including globs. * droprpm Remove matching rpm packages. Dependencies are not remove, just individual packages matching the glob. * keeprpm 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
