I'm not sure it made it up that far - it got to the device rundown
after the initial boot PROM hardware display, then when it normally
goes black right before the grub menu comes up, it never went black.
I created a shell script this morning to do a full system backup to my
two fall-back partitions (one for /boot and one for /), but that only
makes the pain slightly less if the primary fails - at least I should
be able to boot any rescue CD or flash drive, copy the backups over
the primaries and reboot. I hadn't taken that precaution before this
disaster. Difference in time - about an hour of frustration and
I'll keep this in mind if the situation ever comes up again (ha ha ha
- more likely I'll have long forgotten it by then).
