root@dilbert /etc/dump# ./dumpscript 0
/sbin/xfsdump: ERROR: unable to open 
dump@xxxxxxxxxxxxxxxxxx:/local/backup/dump/dilbert-home.dump.0: No such file or 
directory
root@dilbert /etc/dump#

the command the script runs is:

/sbin/xfsdump -F -o -l $1 -f "$TAPE" /home

TAPE="dump@xxxxxxxxxxxxxxxxxx:/local/backup/dump/dilbert-home.dump.$1"

i don't have a tape drive so a regular file is the only option, this
works fine with ext2 dump and as far as i can tell from the docs it
should work with xfsdump as well.

that is not possible, unless i do something hideous like create
symlinks in /dev to the regular files in /local.  i shouldn't have to
do that.
