HD Install :: filesystem

what is the difference between the ext2 filesys and the journalized ext3 filesys, and what is better to use?

ext3 seems to be better when it comes to preventing fragmentation, which can result in corrupted files, but DSL will still mount a root ext3 filesystem as ext2. As far as I know, though, recent improvements to DSL now allow for checking the ext filesystem during boot, which should help prevent these problems.

Journalizing file system only makes sense when deployed on real hard drives.

DSL basically runs from ram and compressed KNOPPIX image, i.e., a worm device. Therefore, it is not efficient to use ext3.

I know some do a traditional hard drive installation, and or a hybrid (persistent). But that is not the default nor design goal of DSL.
