squashfs(: mountable tar.gz) sort option

[Wim Bertels <wim.bertels@khleuven.be>]

Hallo,

u can think of squasfs as a mountable tar.gz (more info on the website
below)

has anyone got experience with the sort option in mksquashfs?

on http://squashfs.sourceforge.net/
in the presentation the sort option is way to optimize compression,
but i didn't find any examples or explainations on how to do that.

For now i've used:

$ ionice -c 3 nice -n 19 mksquashfs dir_to_archive/ archive.squashfs
-comp xz -Xbcj x86 -Xdict-size 75% -always-use-fragments -b 1024

Suggestions to further optimize the compression?

mvg,
Wim
