Im not confident about squashfs, i think the best solution is
initrd.romfs.gz for normal installs, but squashfs or cramfs might be
good for lowmem installs, i havent looked into squashfs yet, not sure
when i will get time.
I have looked at PPMd, ive read thats good but it took me a while to
workout how to use it to get maximum ocmpression, here is a comparison.
8921088 Packages
2375680 Packages.gz
1814528 Packages.bz2
1335296 Packages.pmd
That was done with "PPMd e -o16 -m256 -r2 Packages", it surprised me
that the -m option (amount of memory to use) effects the compression
ratio.
Thats a pretty improvement over bz2.
