- BIG FAT WARNING: ENABLING THIS OPTION MIGHT BREAK BOOTING ON
- SOME DISTRIBUTIONS. DO NOT ENABLE THIS UNLESS YOU KNOW WHAT
- YOU ARE DOING. Distros, please enable this and fix whatever
- is broken.
-
- Conventionally, block device numbers are allocated from
- predetermined contiguous area. However, extended block area
- may introduce non-contiguous block device numbers. This
- option forces most block device numbers to be allocated from
- the extended space and spreads them to discover kernel or
- userland code paths which assume predetermined contiguous
- device number allocation.
-
- Note that turning on this debug option shuffles all the
- device numbers for all IDE and SCSI devices including libata
- ones, so root partition specified using device number
- directly (via rdev or root=MAJ:MIN) won't work anymore.
- Textual device names (root=/dev/sdXn) will continue to work.

- Say N if you are unsure.
