| | | | | | | | | | | | | replace the table of partition with a simpler and faster array of strings. The change in the array is done mechanically, using vi commands. Most entries in the table are probably 15+ years old and largely outdated, so the next step is to remove stale entries with more current values.

* Some small fixes submitted by Christoph Mallon, specifically:Luigi Rizzo2009-01-131-17/+16
| | | | | | | | | | | | | | | | + Remove a dead field of a struct. It serves no purpose anymore. + Remove a \n at the end of the format string of err(); the err() function already adds a \n ; + remove many unnecessary casts which obfuscate the code. This file has a huge number of indentation bugs, but I'd rather fix them when/if we happen to modify the relevant parts of the code.

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

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.

| | | | | | | | | | | | | | | | | | | Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.

| | | | | | | | | | | | | | | | | | | | | | | 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 oldJoerg Wunsch2001-07-131-30/+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. :) Notes: svn path=/head/; revision=79681
