Sounds interesting.

Hard to say, however, I have had some serious crashes with reiserfs. At
one point it blew my partition into pieces, at a reinstall was needed
(reiserfs from kernel 2.4.8).

I know at least that reiser and xfs is - haven't done installation on
xfs/ext3, but it should be easy to find some bootfloppies that do the

I beleive all of them have, it's one of the fine things with journaling

xfs, and ext3 have quota support - I'm not sure about Reiser...
xfs even has acl support (which ext3 doesn't have without some

I might be wrong here - but I beleive that NFS supports every filesystem
that the kernel supports...

And I can only add to this, that my comments aren't ment to start any
flame war either, just sharing some experience and some though.

I would either go with ext3 (which even is ext2 compatible AFAIK) or
XFS. They really seem to be the most stable. Reiser is not bad, but I
have had some terrible experiences with it - however, I do still use it,
it is nice, but IMHO not suited for production systems yet (allthough I
beleive that many people do actually use it in production).
