You can always boot from floppy disk.

Some people _have_ to do hat anyway -- on my system, sash won't run. Too many
INITs I suppose.

No problem.

Things get hairier if you want to put the swap partition onto another disk.
# pname -a -c X -d 0 -s 2 "Swap" # swap partition on SCSI disk w/ ID X
  (The name "Swap" may be different for your system, do
  # dp /dev/dsk/cXd0s31
  ? P
  ? q
  to find out...)
# man kconfig            # :-)
# kconfig -n /unix <<END
  SWAPDEV=0x1C02         # that's /dev/dsk/c4d0s2
  SWAPCNT=xxxx           # whatever
  END
# kconfig /newunix the same way, _or_ do a
# kconfig -a -n /unix >/my.config
  and run
  # kconfig -n /unix </my.config
  after every autoconfig.
