Brad asked about SunOS2. I have no documents for that release, but
SunOS 4s recommended install proceedure bypasses standalone copy in favor
of MUNIX and dd.
To load MUNIX you run
bst()
Boot: st(,,4)
which loads MUNIX into ram. From there, you make devices, if necessary,
run format to label your disks, and then dd the miniroot off with
mt -f /dev/nrst0 fsf3
dd if=/dev/nrst0 of=/dev/rsd0b bs=48k
you boot the miniroot with b sd(,,1) -sw
Standalone copy syntax is
b st()
Boot: st(,,2)
Copy from: st(,,3)
Copy to: st(,,1)
then reset and boot miniroot.
