# This script is used for adding disk drives to AT&T UNIX System V Release 4.0
# It runs adddisk or /etc/scsi/sadddisk to prompt the user for information
# about the disk.  The diskadd program builds the following files:
# /tmp/partitions -- with the disk characteristics and partitions from the
#                    user,
# /tmp/addparts -- contains the names of additional partitions the user may
#                  want in addition to the required standard ones,
# /tmp/mkfs.data -- contains information about each filesystem which the user
#                   wants made.
#
# support is added to call the saddisk command if given a scsi device name
# or if the device name is 1 and it is linked to the scsi dn.
