881c9063c7 Oops, the arguments to a bcopy() were reversed, which broke zeroing
of unused partition entries and later detection of unused entries.

Use memcpy to be consistent with the rest of the code, and fix a
minor style nit.

6369218752 Fix a number of bugs and annoyances in fdisk, many of which were
pointed out by bde:
- Ask for user confirmation before adjusting to a head/cylinder
  boundary (only when running interactively), and separate this
  adjustment from the automatic calculation of c/h/s parameters.
- In sanitize_partition, don't change any values in the slice until
  we know that the automatic adjustment will succeed.
- When auto-adjusting, ignore unused slices and give an appropriate
  error for other zero-size slices depending on the cause.
- Change dos() to do all of the c/h/s calculations for a whole slice;
  this fixes a bug where the ending c/h/s of an unused slice was set
  incorrectly.
- When changing the active slice, detect the currently active slice
  number instead of always defaulting to slice 4.
- Call fflush(stdout) before calling fgets().
- Test for fgets() returning NULL so we don't loop on EOF.

df77f711f3 After some (long-standing ;-) critics from Bruce, throw away the old
device search code i introduce nearly six years ago in rev 1.8.  Bruce
suggested to rather use the device name of the root filesystem instead
which is certainly the most sensible default.  Since there are many
possible cases for a root filesystem name (device with and without
slices, consider /dev/vinum/root even though it currently could not
work as such), there's some heuristic using a RE in order to find out
the canonical device name from the mounted name.  This probably won't
quite fit for a NFS root (can't test that right now), but then,
there's hard to find a good default for those machines anyway. ;-)

This unbreaks the functionality of rev 1.2 i once broke in 1.8. :)

8de9ed220e Make open_disk() fail nicely upon encountering an ENOENT so to not
prematurely terminate the search for a usable disk.  ENOENT is quite
normal in particulare now with the advent of devfs.

While being here, also remove /dev/wd0 and /dev/od0 from the list of
disks to search since we don't have them anymore.

b594e0fea2 - When adjusting the end of a partition to lie on a cylinder boundary, don't
adjust the size, but the actual end.
- Break out some of the sanity checks on partitions into a sanitize_partition
  function.
- When adjusting partitions, always adjust the start "up", and the end "down"
  so that we stay within the boundaries of the original request.
- Various small nits found by bde.

a12de06299 - Don't try to free mboot.bootinst before it has been allocated. If, for
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.

This wipes the MBR and creates slice 1 as a FreeBSD slice covering the

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
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).

e29754402a The dos() function needs a new second argument, containing the size
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.]
