No journaling there, but a system called 'softupdates' that keep
the metadata in sync at the atomic level.  There's an interesting
paper on this - that I think Dr. Seltzer contributed portions too
[she wrote an intereling log file system].

He mentioned FreeBSD and all I did was create a symlink so /appl
was stuffed under /home/filepro, and /home is mounted on 
the /usr filesystem by default.  Worked just fine.

/u  is an SCOism from my observations.
