Well -E would be a darn good start (not knowing any more about it
than you mentioned here). Adding 'hog' to the syntax when editing/using
a label would be nice. Totally revising the syntax would be nice. Perhaps
something like:
# size offset fstype [fsize bsize bps/cpg]
a: 50M 0 4.2BSD 1024 8192 16
b: 100M * swap
c: * 0 unused
f: 500M * 4.2BSD
h: * * vinum
(or maybe h: remaining * for a hog partition, or "hog", etc)
instead of:
# size offset fstype [fsize bsize bps/cpg]
a: 81920 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 84*)
b: 160000 81920 swap # (Cyl. 84* - 218*)
c: 1173930 0 unused 0 0 # (Cyl. 0 - 1211*)
f: 2000000 211920 4.2BSD 1024 8192 16 #
h: 962010 2211920 vinum #
Basically, allow "*" to mean "use the appropriate default", and
allow sizes to be specified in (blocks)/K/M/G.
I have a patch for this that fixes all sorts of other weaknesses in
disklabel in the offing (fully written, not yet fully tested). I got
annoyed at merely discussing this. It also improves error reporting, and
checks for overlapping partitions (excluding 'c' of course).
