I tested the powerdown option to halt(8) this evening on my SPARC Classic
build system. It worked - the system powered down, with the word: "WAR" (I
think it was trying to say, "WARNING: cannot determine keyboard type"
because I use a serial console).

Alas, it apparently did not allow enough time for the disks to flush before
removing power; fsck had some work to do on the root filesystem after
reboot, despite the "syncing disks ... done" message.

I hasten to point out that I have a Quantum Fireball 1080S in this beast,
and this may be a HDA cache-flush issue; Apple had this problem with these
disks a few years ago. Is there an explicit SCSI command to force a disk to
flush its cache to permanent storage?
