lacking the hardware to test if the images would actually work, there
never hasn't been any, sorry.
We face the same problem, obviously. :))
you can ask for porter access on one of the debian machines if you want to.
It would mean boot experiments.
I already shot the foot of George Danchev and myself by pre-maturely
asking for tests with HFS+ on debian-cd. It soon turned out that we
could not get it to boot with qemu-system-ppc. (Further it had to be
adapted to a hardcoded value in Linux kernel mount code.)
We need somebody who is willing to press the reset button (or turn
the yale key in the on-off-reset lock ?).
On a machine that boots the "stable" Debian "powerpc" ISOs.
I am subscribed to debian-cd mailing list. If sincere interest
arises in HFS (without "+") and Debian arch "powerpc", then one
could at least begin to make a plan there.
