Description Bruno Wolff III 2011-02-25 20:24:07 UTC 
Description of problem:
This option should be tested on some sample live images to see what compression gains there are and if they are significant, provide an option on livecd-tools to pass it along with the compression type.

Comment 1 Bruno Wolff III 2011-02-25 20:30:56 UTC 
I should try to get the evaluation done before the F16 alpha, so if there are significant gains still to be had, we can use this for F16 spins.
Comment 2 Bruno Wolff III 2011-02-25 22:21:48 UTC 
I should also test how the dictionary size affects build time and spin size.
Comment 3 Brian Lane 2011-02-25 22:37:09 UTC 
wwoods has been looking into similar things to make the initrd smaller, you should talk to him about this. He's been experimenting with different options for xz.
Comment 4 Jasper O'neal Hartline 2018-06-08 13:13:47 UTC 
Does mksquashfs support lzo/lzma and xz?
Comment 5 Jasper O'neal Hartline 2018-06-08 13:15:36 UTC
