o In Delete_Chunk2(), also look for chunks of type "part" under

type "freebsd" there.
there to support sysinstall, and enabling DEBUG creates spurious
console output that can't be read anyway... This slightly cleans up
the visual impression of the system install by not spamming the console
during the labeling of the disks.
Move the remaining bits of <sys/diskslice.h> to <i386/include/bootinfo.h>
Move i386/pc98 specific bits from <sys/reboot.h> to
<i386/include/bootinfo.h> as well.
Adjust includes in sys/boot accordingly.
- In Create_Chunk_DWIM(), if there is a freebsd chunk that has no
children chunks, then trying to add a child part chunk will fail even
though there is free space. Handle this special case by adding an
unused chunk the full size of the freebsd chunk as a child of the
freebsd chunk before adding the new part chunk. This situation can
happen when changing the type of an existing slice to be a FreeBSD
slice type or when installing onto a blank disk on Alpha (which has
no slices.)

to be cleaner. Also, when deleting a chunk, try to find the mother chunk
as a whole chunk by default if this isn't a BSD partition or a unused or
whole chunk. Before we just did this for FreeBSD and FAT slices, which
means that other chunk types such as EFI and mbr (mbr is used for slices
that don't have their own chunk type).

always to the first 16 sectors of the disk. The firmware reads the boot
code from a partition, defaulting to 'a' if none is specified, which only
corresponds to the first 16 sectors of the disk if 'a' is first. Solaris
often makes the swap partition first, instead of the root partition, and
users expect to be able to do the same with freebsd as well. This also
allows one to temporarily boot from another partition if the boot block
on the root partition gets scrambled somehow.
o Remove all code guarded by !defined(__ia64__). This file is
specifically written for ia64,
o Handle the case when read_block() or write_block() fails. We
don't want sysinstall(8) to signal a thumbs-up on error,
o Set the starting (cyl,hd,sect) triple to 0xFFFFFF when either
bios_hd or bios_sect is zero or the LBA us not representable
with the triple. In that case automaticly initialize the
ending triple with 0xFFFFFF as well,
o Reindent Write_Int32() as it was different than the rest of
the file,
o Remove some unused variables that appeared to be used but
were effectively useless.
o Plug a memory leak: The second timne we read the MBR, we write
out a modified block, but didn't free the memory after writing.
o Replace d1->sector_size with 512 when we read/write the MBR.
We ignore the sector size in cases we shouldn't but adhered to
it in cases it would be wrong if the sector_size wasn't 512.
This file should eventually be rewritten to write out a GPT. For
now, a MBR will do...
to use the same start condition as the i386 version. However, since
Alpha's only have one fake "slice" from sysinstall's perspective we don't
need to use a loop, but can just write out the BSD label in the first
fake "slice".
of heads end the number of sectors per track. If there's an obvious
insanity (heads and sectors are both zero or the media size is not
an integral multiple of heads times sector) we set the number of
cylinders to zero.
1. When the parition type is not an integer, try to parse the type
as an UUID. If that succeeds, map the UUID to chunk_e.
2. For GPT partitions, pass the type constructed in point 1 above
to Add_Chunk.
While here, fix the MBREXT case by only checking if the first 3
characters are MBR. This avoids duplication.
This significantly rewamps libdisks discovery of existing disk

o loosen parsing sanity checks a touch to deal with new xml we must handle
o move sector size probing to non-geom handling since we now get it from xml
o remove WHOLE_DISK_SLICE buggery now that we get mediasize from xml

get what's needed
o replace #ifdef DEBUG constructs with DPRINT/DPRINTX to make the code more

Note the xml "parser" is very very hackish and should be replaced with a
real one. This one was done to be very small and special-purpose; don't
think about copying it elsewhere.

o memory wasn't reclaimed in certain cases

o rewrite tangle of for loops for clarity
NB: Open_Disk should redo how it malloc's memory so the caller can free
everything. Documentation says the caller can free the disk list to
reclaim everything but this leaks the indirect strings. Fixing this
is simple for the sysctl case but adds complexity to the fallback,
non-sysctl, case.
Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.
These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.
This commit adds a number of such #includes.
Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

argument. Leave a compatibility shim for Delete_Chunk().
Implement DELCHUNK_RECOVER flag so sysinstall can ask libdisk
to recover space when deleting a chunk.
sysinstall will automatically expand the previous partition to take up
the freed up space. So you can 'D'elete /home and /usr will get the
combined space, or you can 'D'elete /tmp and /var will get the combined space.
This gives the user, developer, or lay person a huge amount of flexibility
in constructing partitions from an 'A'uto base. It takes only 3 or 4
keystrokes to achieve virtually any combination of having or not having
a /tmp and/or /home after doing an 'A'uto create.
Change 'A'uto creation of /var/tmp to 'A'uto creation /tmp, which should
be less controversial.
