a PMBR. Make sure the create command creates a PMBR as well
(if not already present).
o When parsing the MBR, explicitly check for a PMBR and create
a PMBR map node if one is found.
o When parsing the MBR, recurse to handle extended partitions.
This allows us to flatten nested MBRs when migrating to a
GPT.
o Have the migrate command bail out if it encounters a partition
it doesn't know how to migrate. This avoids data loss.
o Change the output of the show command so that the UUIDs of the
GPT partitions fit on the same line.
o Show when partitions are extended partitions and add the PMBR
type.

the newfs default is for the platform (generally, UFS1). This is
required to support diskless workstations that use UFS2 for their
mdmfs file systems.

UUIDs can then be limited to those cases when an alias doesn't exist.
This greatly increases the likelyhood that a sysadmin finishes the
partitioning without intermittent mental breakdowns. Current aliases
are "efi", "swap" and "ufs".
While here, staticize global variables and expand the usage message.

the MAXBSIZE blocksize limit. This update also fixes a problem where
newfs could segment fault if the selected fragment size was too large.

the old 8-bit fs_old_flags to the new location the first time that the
filesystem is mounted by a new kernel. One of the unused flags in
fs_old_flags is used to indicate that the flags have been moved.
Leave the fs_old_flags word intact so that it will work properly if
used on an old kernel.
Change the fs_sblockloc superblock location field to be in units
of bytes instead of in units of filesystem fragments. The old units
did not work properly when the fragment size exceeeded the superblock
size (8192). Update old fs_sblockloc values at the same time that
the flags are moved.

It seems a common corruption to have them -ve (I've seen it several times)
and if fsck doesn't fix it, it leads to a kernel pagefault.

the primary use of this program is to format floppy disks.
