some reason, mboot.bootinst is not initialized to NULL at the beginning
of the program, then the last commit to this would try to free whatever
bogus address is in it.
- Restore the behavior of free()'ing the mboot.bootinst buffer after we
abuse it to determine the sector size of the disk (as clearly noted in
the comments). Properly fix the double free() bug by setting the pointer
to NULL after we free it.
explicitly sets the geometry.
- Allow for MBR boot loaders that are longer than one sector. Only accept
boot loaders if their size is a multiple of the sector size, however.
This wipes the MBR and creates slice 1 as a FreeBSD slice covering the
disk starting from the second track to the cylinder aligned end of the disk.
This is the most compatibly layout we have as far as I know.
the boot code from /boot/mbr, or elsewhere as defined by the revised
"-b bootcode" option; use getopt(3); clarify usage(); partially
revise man page; etc.
I don't have access to a BSD/OS machine to check the veracity of the
magic number. However, no harm will be done by the commit and since
someone was motivated enough to file a PR, I'm committing the change.

Add "." at the end of some sentances.
Also print "flag 80" in English.
Give hint that "sysid" for FreeBSD is 165 decimal.
Ensure active partition specified by user is 1-4.
Any existing config files (using the -f option) will need
to be changed although using the old files will usually result
in an error (partition 0 is invalid).
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

of the partition. Only if the size is 0 should the
special handling of 0 as first argument be triggered.
[This bug caused offset 0 to give C/H/S = 0/0/0 instead of 0/0/1.]
The init_sector0 function needs to decrease the first argument
to the second call to dos() by one to be consistent with the
calls to dos() in change_part().
[This bug caused fdisk -i to create bogus partition tables with
the ending C/H/S value 1 too high. This usually gives S = 1
instead of S = maximum, so the geometry guessing in the slice
code and perhaps in SCSI BIOSes was defeated.]

Scan a list of devices instead of insisting on all the world

Allow for disk names to be specified (e.g. `sd0') instead of full
path names only.
Sync the man page with the reality.
device driver cannot supply a label (real or faked). This allows
you to practice using fdisk on disposable media (e.g., "dd count=1
<dev/zero >/tmp/junk; fdisk /tmp/junk", "dd count=1 </etc/passwd
>/tmp/fix-up-the-mess; fdisk /tmp/fix-up-the-mess") and allows me
to test DOSpartitioning and labelling on floppies.
