S/390 and whatever the "don't-really-reboot" flag is
As I understand it, the "run /sbin/reboot or not" flag in d-i is kind of
in flux.
It was put there for embedded devices, because reboot repeats the last
boot you did, which will, in those devices, boot from the wrong thing.
This is also the case in the S/390 install: you will have booted (IPLed,
in the S/390 world) the installer from either a (virtual) card deck or a
tape. If you run /sbin/reboot, you use the same thing again. That will
run the installer again (or fail, if the card reader wasn't set to hang
on to its decks or the tape wasn't rewound) rather than booting the
installed system, which isn't what we want.
Instead we want to simply halt the system and instruct the user to IPL
from the disk (DASD in S/390-speak) device that the boot record was
written to.
What's the right way to tell d-i this for S/390?
