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.
17
19 usage: image-minimizer [-h] [-i STRING] [--dryrun] [-v] STRING
20
21 Optional arguments
22 -h, --help
23 show this help message and exit
24
25 -i STRING, --installroot STRING
26 Root path to prepend to all file patterns and installation
27 root for RPM operations. Defaults to INSTALL_ROOT or
28 /mnt/sysimage/
29
30 --dryrun
31 If set, no filesystem changes are made.
32
33 -v, --verbose
34 Display every action as it is performed.
35
36 Positional arguments
37 STRING Filename to process

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.
51
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.

70 Example Anaconda %post usage:
71
72 %post --interpreter=image-minimizer --nochroot

75 keep /lib/modules/*/kernel/fs/ext*
76 keep /lib/modules/*/kernel/fs/mbcache*
77 keep /lib/modules/*/kernel/fs/squashfs
