Yes.

I'm still a little confused by this.  In Gentoo at least, yaboot does not
require a /boot partition, but it does require the apple bootstrap
partition.  This is created by using the 'b' command in mac-fdisk, which
creates an 800k HFS partition.  Once created, mkofboot is run to format
the bootstrap partition and copy the yaboot files to it.  This is the
location where I put the grubof.modules and grub.cfg files.

For grub to work, does this partition need to be larger and then mounted
as /boot in Linux?

Or do I need a separate /boot partition, but it must be an HFS partition?

Can I see your /etc/fstab and partition map?  It might be easier for me to
just duplicate what you have.  Once I get it working, I can figure out
exactly what the requirements are.  For what its worth, I'm setting this
up on a MacMini with 256MB.  Not sure if that should make a difference.

I did try setting up separate /boot and /boot/grub partitions, but didn't
think these needed to be HFS.  I assumed that once grub was running from
the bootstrap partition it was no longer neccessary to stay within HFS.

Have you looked into this yet?  I was hoping to dig through the code
before sending this email :)  I feel like I'm doing something
fundamentally wrong and it might be easier just following the logic..

Thanks,
