GNU Parted, linuxppc support coming :-)

Hi all,

I've started hacking on linuxppc (on Macs) support for GNU Parted, a
partition program.  It's like fdisk (or pdisk), but it can also
create, copy and resize file systems that it has special support for.
More info at:

	www.gnu.org/software/parted

I'm trying to support the Mac partition map, but I'll need some help,
since I don't have a PowerPC :-(

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?)

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...

Of course, I'd also be happy very if someone could help with the code,
or just testing :-)

Thanks!

Does parted support Amiga partition maps?

No.  Not yet ;-)

If not, I'm sure APUS users will gladly send you their partition
maps...

I'm not ready for that yet :-/  Are there any good docs around?

Thanks!

Just about everything you need is at

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.

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...)

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 :-)
