It was yesterday. Today I remounted it rw to remove some junk-files,
which I don't need to transfer. I don't believe, this is causing the
problems.

I don't think, restore can even figure this out, much less throw a
warning -- it is dump, that complains... But the dump started this
morning is still hanging (in sbwait) -- I've never seen this before. I'm
also very troubled, that such an important functionality (dump/restore!)
is sooo problem-prone, and yet so few people seem to care...
Is the official view, that dump is obsolete (and already bit-rotten),
perhaps, and use of tar is encouraged instead?
