	Setld is supposed to be stupid so you don't need a PhD to
	install your system - maybe it should have a '-PhD' option
	so we can do all the little tricks everyone ends up needing
	after they have figured out they don't have 70meg of free
	disk space required to remote load 300k to a host. A plain
	vanilla install of Ultrix is painless if a bit long (using
	a tk50) - setld is a helluva shell script and fun to read,
	if you like shell scripts.  I would like
 	to see remote tapes supported officially [ fairly trivial
	to put it in yourself] and have the '-x' option support
	a subset_by_name request (making this discussion not needed)
	anyway - add this to what Fred has already said:

	You can use setld -x to unload a 
	complete tape in image format or you can read the image
	file to find out how far in to 'mt fsf' to get the image
	you want then you can

	 'dd if=/dev/nrmt0h ibs=10k |uncompress | tar xvbfp 20 -'

	or(if you have loaded the SUBSET_NAME to disk with setld -x):

	 'cat SUBSET_NAME |uncompress | tar xvbfp 20 -'


	As the tar file is compressed and then put on the tape
	at 10k blocks, the uncompressed format is 20b (the default
	for tar so you probably can leave the 'b 20' out)
