The console program is limited to 1.073GB - anything beyond that
wraps round, which could be quite embarrassing!=20

OpenVMS uses the console's boot driver's until relatively late
in the boot process, so you have to do a certain amount of
(unsupported) jiggery-pokery to be sure it will work. Worse still,
OpenVMS assumes that the console disk drivers, being in EPROM and
hence theoretically a bit like Caesar's wife (incorruptible), are
more trustworthy when it comes to writing out a crash dump. So that's
another nasty you need to worry about.

With NetBSD you can partition the disk to avoid the problem - at least
I expect you can. The same is likely to be true of Linux (and probably
Ultrix).
