`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.

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.
