I downgraded to Amanda 2.5.2p1 and it gave me a better clue when running amlabel. Basically it said /dev/nst0 = permission denied. I've been running the amlabel command as amandabackup but didn't realize you need to give permissions to the /dev/nst0 device (which was 750 perms and owned by root:root). I chmod'd to 777 to test and that fixed the problem.

Is it a known deal that we're supposed to change permission on the tape dev name?

The mystery deepens.

Can you run 'amlabel' under strace or truss or your local equivalent?
I'd like to know what syscall is returning EBADFD (Bad file
descriptor). Also, please remind me what version of Amanda you're
running.

You can send the strace output to me privately for analysis if you'd
like, rather than spamming the list (it will be *large*)
