That's an interesting question.  This server has been through a
goodly few incarnations, over many years.  Once upon a time it
was running 3.4 or there abouts.  I thought that I had re-built
it from scratch the last time (to 5.3), which presumably would
have given me UFS2, but the possibility exists...

How would I be able to tell?  tunefs -p lists ACLs and MAC
multlabel and soft updates, but of those only soft updates is
enabled, so I don't know if that is conclusive.  Did UFS2 give
us anything beyond ACLs and largeness?  bsdlabel, mount and df
don't seem to give any particular indication...

Cheers,
