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?

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...
