. Implement option -c, all partition sizes will be calculated
in cylinders as opposed to sectors. Since the Sun label is
inherently cylinder-based, this makes the job a little easier.
. Implement option -h, print the label in `human readable'
size/offset format.
. Implement SVR4-compatible VTOC-style elements. They are
fully optional, defaulting to the current behaviour where no
VTOC-style table will be written to disk. However, if
desired, the full functionality of the partitioning menu of
Solaris' format(1m) is now offered (and even more).
. When editing the label, do not loop around edit_label() where
a new template file is generated for each turn, this used to
be annoying in that any possible syntax error caused a
complaint, but then the template was created anew, so the
user had to perform all their editing again. Rather loop
inside edit_label(), similar to bsdlabel(8), so in case of
errors, the user will be presented their previous template
file again.
. If VTOC-style elements are present, the overlap checks are
made less stringent. Overlaps will still be warned about,
but overlaps of `unmountable' partitions against other ones
are no longer fatal. That way, e. g. VxVM encapsulated
disk labels can be fully edited in FreeBSD (but not in
Solaris ;-).
. In print_label(), generate the editing hints only if the -e
flag is in effect. Additionally, print a hint about the
total number of sectors in the (hardware) medium.
. When editing a label, allow for changing the geometry
emulation (and textual name) by modifying the "text:" line
on top. That way, a more effective emulation can be
chosen.
. When editing/reading a label, additionally allow for the
suffixes `s' (512-byte sectors), and `c' (cylinders) in the
partition size field.
. Finally, turn the stub man page into something that really
explains the entire thing.
violate POLA a little less by not requiring exactly two spaces in front
of the entry (and silently discarding any non-matching entry). We now
recognize anything starting with a letter followed by a colon as the
first non-space chars as a partition entry.
hinge on the "verb" parameter which the class gets to interpret as
it sees fit.
Move the entire request into the kernel and move changed parameters
back when done.
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.
