Cannot boot from external drive where superduper smart copies

[dnanian]

Actually, please do *not* do this. That's not the problem in this case: the problem, based on our initial work in email, is that the Netinfo database on the source volume is corrupt.

Do NOT check "ignore permissions", as it will mess things up, OK?

Bagleturf: really, that's not a good idea. A cloned boot volume should never have its permissions/ownership turned off, as doing so will cause the OS to do some very unusual and not-very-helpful things, like start floating files... I don't know why it worked in your case, but it shouldn't have done anything useful.

It's likely that re-doing your backup is what really repaired things, but in this case that won't help because we're copying incorrect data.

Hope that helps. I'll put more on this thread when we've resolved the problem.
