I still don't see the situations where its a big disadvantage. The format
of an AFS volume file is just as opaque to me as an umounted filesystem
block device. If its get to the point where I'm digging through /dev/sda1
trying to fix something on the filesystem I'm much better off wiping the
system, reinstalling and recovering from backups if I need to. Same goes
for AFS. I can't think of any use cases of ripping apart the on-disk
format of a volume that aren't better addressed through some other tactic
that is less of a waste of my time.
