Due to a combination of my s
tupidity and external vents, a machine running -Current from late April
will no longer boot. Specifically, instead of the loader screen I get
"Invaslid partition".
Crud.
Broke out the most recent fixit disk, which is from 7.1 (Jan 2009).
Boots fine; fdisk finds the correct slice information; bsdlabel
finds the right partition data; mount / and /usr under LiveFS
Whew!!!!
So ... I'm guessing the problem in the boot code is corrupted, and
if I do
fdisk -B -b <path to -CURRENT boot blocks> da0
However: when I do the second commit I get
fdisk: Geom not found "da0"
fdsk: failed to write sector 0
This leads to the assumption there is a fundamental discrepancy
between the two versions. Not unreasonable, ans I know there have been
changes in the code since 7.1.
0) is the diagnosis correct, and will my proposed solution work
1) if so, is there a way to convince the 7.1 fdisk to Do The Right
Thing?
2) if not, what do I do next?
