    I am gettin gthe impression that dump is more of a file archiver rather than a
    true system backup utility.

    a noted shortcoming on our part. it wasn't broken so we didn't try to fix
    (aside from a few patches), which evidently came back to haunt us when a repair
    of this magnitute was required.

    The dissapointment (or misunderstanding on my part of what dump/restore could
    handle) is that the hardware was identical, including the new hard drive
    make/model. Absolutely nothing had changed, it just didn't seem up to the task
    of restoring over a basic file system.

    one of those "never know if it works untill you have a disaster"... well we had
    one, and it didn't.
