# This script is used for adding disk drives to
# System V.3 on the Intel AT/386.  It runs adddisk to prompt the
# user for information about his disk and partitions thereon.  The
# diskadd program builds the following files:
# /tmp/partitions -- with the disk characteristics and partitions from the
#                    user,
# /tmp/fdisk.data -- used as re-directed input to fdisk to set aside a Unix
#                    area on the disk,
# /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.
# /tmp/diskname -- the tail of the device stanza generated in adddisk and
#                  the name of the raw disk device for it.
