Generally ext3 will do you fine. If you absolutely ***NEED*** the
speed of XFS, chances are that you've already learned enough to be
able to deal with it (grub, I'm looking at YOU).
I've used XFS before, and it's a nice FS, however, it does have some
limitations. Foremost, it's not grub compatible, and lilo is just
plain weird. I learned how to use Lilo, however, stick with grub if
Second XFS is rather old. New versions aren't being merged into the
kernel until the XFS folks start making mods that adhere to the Linux
Kernel standards (particularly negative error codes, etc). XFS is
reluctant to do that because it digresses from their IRIX codebase. I
don't blame them that much, 'cause I personally strolled through that
code to try and do it myself for the LKJ, and was thoroughly confused
in a very short time.
I was also under the impression that XFS is less tolerant of
corruption due to its more sensitive data structure (a B-Tree), though
that could just be me imagining things.
