:Hello,
:
:hmm, once again me. And again with a probably not so common problem.
:I need to replicate files, exactly like they are!
:I thought cpio was the deal, but no way, I tried several -H formats but=20
:that hasn't changed anything. As soon as a file gets restored the flag=20
:...
:Thank you, I know cpdup but I haven't known that it's flags aware!
:Unfortunately I need to write to a raw device, I guess there's no way for=20
:cpdup without a filesystem...

:I guess cpio and tar really should take care about flags. Am I wrong?

:Thanks,
