It is nice to be able to drop a new scsi drive on the bus and run install
(and get all the sets from a directory on currently running, booted drive).
Then change a few numbers in /newdrive/etc/fstab, pull the drive off, change
its scis id, and put it in a new machine.

Unfortunately, the install script cannot get the sets from an already
mounted drive.

Could a feature be added to install so that it gets the install sets from
a directory (specified by the user, of coarse) on the currently mounted
filesystem?
