This should probably also note the issue with stale disklabels from
old
DD mode disks, which causes the machine to be unbootable. It should
also mention the "geometry does not match label (255h,63s != 16h,
63s)"
message (which appears to be harmless), and it should also probably
mention that the c partition now covers the entire disk, not just the
"DOS partition"... And it should be noted that these changes took
place
in Decemeber, so that people have a better chance of knowing if
they are
going to be bitten.
Ok. Should I re-sort the note into December (probably not since it
mentions development from a large period) or just mention it in text?
I would mention it in text.
@Marcel: is the warning important (I didn't encounter it yet; I guess
it probably a quirk of UFS?)
The warning could be important. It also makes us aware that
there's a discrepancy, which indicates that we have bugs.
and is the "c" change intended?
The only change is that the 'c' partition cannot be used directly
anymore. If you want the whole disk, you use the provider. The
meaning of 'c' didn't change.
(isn't it
time to abandon the special case of "c"?)
I chose to hide 'c' rather than give it a new meaning. The
reason being that disklabel/bsdlabel still assumes the old
meaning. By hiding the 'c' partition we avoid that people
abuse the 'c' partition. There's no need to abuse 'c'
anymore because the partition table can hold 20 partitions
instead of 8.
