* Use symbolic constants from <sys/diskmbr.h> instead of local constants.phk2003-04-131-13/+15
| | | | | | | | | | | | | | | | | | 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.

* Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:phk2002-10-011-0/+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.

| | | | | | | | | | | | | | | | | | | | 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.

* After some (long-standing ;-) critics from Bruce, throw away the oldjoerg2001-07-131-30/+60
| | | | | | | | | | | | | | 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. :)
