Comment 2 Urmas 2012-10-28 21:35:38 UTC 
Apparently a using of XZ compression can yield a few megabytes for Loonix distribution.
Comment 3 Rene Engelhard 2012-10-28 22:03:18 UTC 
note that Debian itself does this already since some time: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687041

Measurements at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687041#17
Comment 4 Jérôme 2012-10-29 19:54:39 UTC 
The maximum compression rate is achieved with "-9e" options : see man page of xz.
