but the greatest use of reiserfs is that it stores metadata in a b-tree. For use on filesystems with many files (mostly small) it also saves them _in_ the b-tree. This speeds up read/create/delete speed hugely. Swithcing /usr from ext2 (4k blocks) to reiserfs here saved over 20 megs. I usually run the bleading edge kernels (2.4.x-prex) and reboots are much nicer using the aformentioned journaling. If you just want to use journaling, I would suggest using ext3, as you can upgrade and downgrade existing ext2 partitions without (hopfully) loseing a single file. That said, it is still beta code. > There are several other advanced/journaling file systems for linux under > development.

I have yet to have data loss on reiserfs...but have under ext2. That has more to do with inexperice then code maturity. Install software knows more about ext2 then anyother fs, so that probably limits what you can use now. Thomas
