I guess I must have been asleep during my sys-admin class when they
discussed devices;) Even after many years of doing this, I only seem to
have a peripheral knowledge of devices and how they truly work. Anyway,
in this case, the 'r' device isn't documented in the sa (4) man page, so I
guess that was where my confusion came in, but after trying the /dev/nrsa0
device, Amanda seems to work like the champ it is. I'm assuming 'nrsa0'
means non-rewind+raw device, which in retrospect is why the kernel was
giving that error when I used 'nsa0' and Amanda probably tried to rewind
it to check the label.
Thanks all.
