vs 4), supress all unused partition output unless -v is specified.
This makes operating on a 'typical' disk with one partition less
painful. The 30 lines needed for the empty partitions no longer
scroll the useful information off the screen. When the user requests
a specific partition, the unused information is not suppressed.
Also add the partition name to the -s output.
Initialize the partition name to 'FreeBSD' when -I is specified.
o Merge the -I switch from i386 verison to initialize the partition table
to use the maximum amount possible for a single FreeBSD table.
o Improve warning when the geom method fails (which I think it
always will until geom_pc98 is updated to respond to this ctl message)
o when writing out the boot sector, we have to write out a minimum of
1024 bytes or the sector size. This is different than the i386 case where
we need to write out a minimum of 512 bytes (which is also the minimum
sector size). We already handle this difference on reading, but didn't
in writing, so attempting to write a new partition table would fail.
o Add MID to the -s output, since pc98 users are likely interested in
both of these parameters.
# I can now initialize disks on my pc98 machine either by -I or by
# manually entering the parameters. I don't know if fdisk -B works or not,
# since I'm not willing to risk my only working boot disk to test it..
