table. Useful if the disk has remapping drivers installed into it (such as
Ontrack Disk Manager).
Added as an option instead of automatic behavior to let the user scan any
of the two partition tables at will.
-w write in-core label if changed
-r update on-disk as well as in-core label (with -w)
-f force update (-w), even if there's been no change
-r behaviour suggested by matt green. what used to be `-f' is now `-wrf'
gotten bitten by mbrlabel trashing my incore disklabel to a point where
the machine wasn't usable, so I reworked it:
* only update the incore (and on-disk) label if `-f' is given. by default,
the proposed disklabel will be printed but no changes will occur
* add -q, to make the default operation a bit more quiet.
* leave existing `used' in-core partition slots alone, and only add entries
to the incore label if:
- there's not an existing partition of the same size and offset
(even of a different type)
- there's a free partition slot (`unused', with size == 0)
* use DIOCWDINFO instead of DIOCSDINFO, to update the incore as well as
the on-disk label
* use showpartitions() from ../disklabel/printlabel.c
this should make mbrlabel a *lot* more useful.
