The experience with a lot of people with ReiserFS is that it's great and
fast until something goes wrong, and then it's a disaster. At this point,
the file system also has a questionable future, and the kernel developers
are leery of it. That's enough to make me want to go somewhere else for a

My personal take on file systems is that smallish differentials in speed
aren't worth worrying about compared to robustness and reliability, so I
tend to run the most mainstream, most widely-used file system on whatever
platform I'm using rather than try to squeeze a bit of additional
peroformance by running something a bit more edgy. Right now, ext3 is the
middle of the road and I think the safe choice.
XFS is a lot better than ReiserFS, though, in terms of support and
knowledge by the kernel developers, and would probably be fine. It is
faster for a lot of usage profiles than ext3.

Documentation for CellAlias has been missing for a long time, but it's
getting there slowly.

Right. :) I got caught recently the same way, actually.

Certainly. I wish I knew more concrete details about what could have gone
