I'm trying to support the Mac partition map, but I'll need some help,
since I don't have a PowerPC :-(
Just about everything you need is at
http://developer.apple.com/techpubs/mac/Devices/Devices-121.html#HEADING121-50
Yeah, I've read it... :-)
At least, I know that myself and a few other people have been able to
code based off of that.
Yep.

Could someone send me their partition map?  You can get this with:

        # dd if=/dev/hda bs=512 count=MAP-SIZE | gzip | map.gz

If you don't know how big your partition map (+1 for driver block) is,
then 64 should do (?).  (What's a reasonable size for a partition
map?)
I forget, but I don't think *anyone* has more than 20 (on most Macs, the
first 7 contain drivers etc), so 20 x sizeof(partition) (see above URL).
Each partition gets one block (yes?).  So thats 20 * 512?
(From comments in various programs, most disks have 512 byte blocks...)

Note: I'm not adding HFS support at this stage - it's a LOT of work.
So you'll be able to resize ext2 partitions in the near future, but
not HFS partitions :-/  Unless there are some volunteers...
There seems to be a shortage of HFS folks these days. :) But ext2
resizing sounds very cool.
Excuse my ignorance... what FS's do people usually use with MacOS?
HFS/HFS+?

(Is the point "no-one uses MacOS", or "no-one's hacking on HFS
in Linux"?)
P.S. Can't get you a real map right now, but email me later if you want
it.
That would be useful, thanks :-)
