<p>You cannot pass any arguments to <cite>image-minimizer</cite> when using it from the
|
||
|
|
kickstart <cite>%post</cite>.</p>
|
||
|
|
<p>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 <cite>lorax</cite> in
|
||
|
|
the <cite>%package</cite> section. You can use <cite>image-minimizer</cite> to remove lorax from the install.</p>
|
||
|
|
<p>If you are using this with <cite>livemedia-creator</cite> it can be installed on the host
|
||
|
|
system so that <cite>lorax</cite> isn't needed in the <cite>%package</cite> list, and it doesn't need
|
||
|
|
to be removed.</p>

package, file, or glob. The globs used are Unix style pathname patterns using

<cite>*</cite>, <cite>?</cite>, and <cite>[]</cite> character ranges. globbing is implemented using the python

|
|
glob module.</p>
