You can set DEV_PREFIX and RDEV_PREFIX before configuration.
DEV_PREFIX=/dev/md/dsk/
RDEV_PREFIX=/dev/md/rdsk/
./configure ....

But then you will have to use the full pathname for disk in /dev/dsk

It could be possible to patch amanda to check in /dev/dsk and /dev/md/dsk
but you will not know if amanda backup /dev/dsk/d14 or /dev/md/dsk/d14

It think it's nicer when you know what get dumped, that's why a prefer
to use full pathname in my disklist.
