That is basically what we are doing, using the things that worked for us with
AFS and trying to avoid a few things that we had in the AFS tree that
we didn't like or were obsolete. UFS filesets shouldn't be any different
than LFS ones except that you don't have as much granularity wrt ACLs,
quotas, etc. We have found it useful to mount our UFS filesets under
a directory in an LFS fileset so that we can use ACLs on the directory
to control access to the UFS fileset. I agree that for new data you
might as well just use LFS though. Where UFS is coming in handy for us
is incorporating data currently being accessed via NFS mounts into our
DFS cell.
