Not a particularly good assumption.  We run several file servers on
single-processor Solaris 8 systems.  (Eventually we'll move to Linux, but
I don't know when.)

However, we're running into some problems with file server crashes on
Solaris 8 with 1.4.0 as well.  We're currently working on figuring out
what's going on.

You shouldn't have to salvage if you do a clean restart with bos restart
-bosserver.  The only delay is breaking callbacks and attaching volumes.
(Which admittedly isn't always fast.)

Those are really the advantages of using bosserver.  Personally, I think
having the bos command suite is fairly important.  :)

If you wanted to, you could run everything under something like
daemontools.  You just wouldn't get the network management.
