Hi Bob,
It is necessary to look at all the factors which
might result in data
loss before deciding what the most effective steps
are to minimize
the probability of loss.

Yes, in /proc/*/path (kinda).
But that could be slow if you have large directories so you have to
think about where you would use it.
The kernel caches file names; however, it cannot be use for

Thank you. I was not aware that root pools could not be moved.

You do know that OpenSolaris + VirtualBox can trash your ZFS raid? You can
loose your data. There is a post about write cache and ZFS and VirtualbBox, I
think you need to disable it?
