Sorry, I should've read the question more carefully. Perhaps JFFS2 works on USB flash after all? Besides btrfs which is very primitive ATM, I don't know other compressed FSs. 2009/7/7 Luke Faraone : > On Mon, Jul 6, 2009 at 21:00, Lucian Branescu > wrote: >> >> Basically any FS that works on all

USB flash drives have controllers that do wear-leveling. They try really hard to make them look like hard drives. JFFS2 works on raw flash, so it's not useful. Basically any FS that works on all the OSes you need. ext2 is a good option. NTFS might be, but it's fiddly. I've tried to get a UDF file
