Is Ext2 journalled or was that Ext3? Just thinking it might wear out an RW disk faster if a journalled system was used. If Ext2 is not journalled then why not use it? Unless it is less efficient than UFS? Sorry answered with more questions...

EXT3 is the -j (journal) flag of EXT2... if you're really interested in file systems look at Btrfs - it's a promising one for the future... reiser will eventually become a dead fs as the creator is serving life in jail (i reckon that'll have been the nail in the coffin of the fs!) if anyone's interested... i believe the guy murdered his family or something?

SuSE is still using Reiser, but i believe that novell are supporting btrfs... so thats a good possibility in the future EXT4 is marked as stable in the kernel now by the way, as of 2.6.28 (i think) so keep an eye on that!
