INSTALL.macppc -snapshot questions

[Brian <bwaichu_(_at_)_yahoo_(_dot_)_com>]

I am reading through the installation manual, and some pieces of the
manual don't make sense to me.

Here are my assumptions:

1) pdisk is used to partition HFS partitions
2) fdisk is used to partition bsd partitions
3) disklabel is used to create slices

If I am using the mac to only run openBSD, I do not need to mess with
pdisk, right?  I would do the install the same way as on an i386 with
the exception of making the following changes to the firmwear:

setenv auto-boot? true
setenv boot-device hd:,ofwboot

[to save the results into NVRAM]
reset-all

(per ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/macppc/INSTALL.macppc)

If I want to share the drive with OS X, then I would need to use pdisk
to partition a part of the drive for openBSD?  This would probably call
for doing a fresh install of OS X with only a part of the drive
partitioned, right?

Now, in the documentation, I am getting confused here:

"Next the disk label which defines the layout of the OpenBSD
file systems must be set up.  The installation script will
invoke an interactive editor allowing you to do this.  Note
that partition 'c' inside this disk label should ALWAYS
reflect the entire disk, including any non-OpenBSD portions.
If you are labeling a new disk, you will probably start
out with an 'a' partition that spans the disk.  In this
case you should delete 'a' before adding new partitions.
The root file system should be in partition 'a', and swap
is usually in partition 'b'. If you have DOS or Linux
partitions defined on the disk, these will usually show up as
partition 'h', 'i' and so on."

Shouldn't all the references to partition 'letter' say slice instead?

Anyway, thanks for helping with this transition.  I really need a new
box to do some of the things I have been putting on hold.

Thanks,

Brian
