10
11       image-minimizer  is a script used as an interpreter for kickstart %post
12       sections. It is used to remove rpm packages and individual  files  from
13       the system that Anaconda has just installed.
14
15       It processes a list of commands that tell it which files or rpms to re‐
16       move, and which to keep.

NOTES

40       You cannot pass any arguments to image-minimizer when using it from the
41       kickstart %post.
42
43       When  using  this from a kickstart the image-minimizer package needs to
44       be available.  It is not included on the standard boot.iso, so you will
45       need  to include lorax in the %package section. You can use image-mini‐
46       mizer to remove lorax from the install.
47
48       If you are using this with livemedia-creator it can be installed on the
49       host  system  so  that  lorax isn't needed in the %package list, and it
50       doesn't need to be removed.

COMMANDS

53       Commands are listed one per line, followed by a space, and then by  the
54       package,  file,  or  glob.  The globs used are Unix style pathname pat‐
55       terns using *, ?, and [] character ranges. globbing is implemented  us‐
56       ing the python glob module.
57
58       • drop <PATTERN> This will remove files from the installation.
59
60       • keep  <PATTERN> This will keep files, and should follow any drop com‐
61         mands including globs.
62
63       • droprpm <PATTERN> Remove matching rpm packages. Dependencies are  not
64         remove, just individual packages matching the glob.
65
66       • keeprpm <PATTERN> Do not remove matching rpm packages, it should fol‐
67         low any droprpm commands that include globs.
