24e3ce108a o Add -p flag: print a slice table in fdisk configuration file format.
Now it is possible to do something like fdisk -p ad0 | fdisk -f - ad1.

80d29aa8a8 - Fail with an understandable error message if we cannot detect the
sector size, instead of later failing with an error about /boot/mbr
  not being a multiple of the sector size (since we end up with an
  assumed sector size of MAX_SEC_SIZE * 2).
- We query the sector size via an IOCTL anyway, so if that succeeds
  use that instead of probing for it via read(2) calls.  This fixes
  the problem with fdisk failing to operate on at least graid3 and
  md(4) devices on kernels with src/sys/geom/geom_dev.c before
  rev. 1.90, due to fdisk failing to detect the sector size.
- When detecting the root device allow "/" characters in it, which
  happens with e.g. gmirror devices.

a9021891fc Use symbolic constants from <sys/diskmbr.h> instead of local constants.
Always set the magic sequence when we write, rather than trusting the
previously read boot code to do so.

Use explicit encoding/decoding of little endian disk image.

Remove a comment which was OBE.

Change the test vector for "fdisk -I" to reflect that there is a magic
sequence in the result now.

Add test case for "fdisk" which reads the image back.

At least for the two test-cases this program now gives the same result
on sparc64 as on i386.  The lack of an installed /boot/mbr on sparc64
raises an (un)interesting question.

19150ba4f8 Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:
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.

4c37b1678b 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.

43c5cead2a 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. :)
