XFS is typically considered a better filesystem than ext*fs's, and it 
has recently had read-only support ported to FreeBSD.  If you desire 
write support for it, you might offer help to the developers that worked 
so hard on the current state of XFS.

As far as a native journaling fs for FreeBSD, Scott Long and a SoC 
developer started work on a jUFS, but I'm not certain as to the status.  
I too am very anxious for it, and would like to play with the code as it 
is so far, but I can't seem to easily check it out of perforce (no 
login, of course).

Maybe Scott can give us a quick update?
