Modified files:
sbin/sunlabel sunlabel.c
Log:
- Use read(2) to get the existing sunlabel on a disk, instead of parsing
kern.geom.conftxt, which md disks don't show up in. If the magic and
the checksum are right assume its a valid sunlabel, otherwise use the
DIOC ioctls to get the disk parameters and whip up a label out of thin
air.
- Don't just silently create or correct invalid c partitions, warn about
invalid ones in label proto files.
- Split checksumming into a function since we do it a couple times. Also
don't include the sl_cksum field in the checksum, which avoids needing
to clear it first.
This is makes sunlabel a suitable replacement for disklabel in make release.
