Definitely not "faithfully recreated" - restore uses standard filesystem
calls (the same as any other normal application) to write the files it
is recovering (transferring in this usage) - and while dump (since it
reads from the raw device) could conceivably send something that made
no sense, all restore can do in that case is complain - it has no
mechanism to create faulty filesystem data.
What version system (and what update date if it is HEAD, or anything_STABLE)
was used for this?
