I have 2 Mac Pro G5's and was testing out FreeBSD 9.1 beta. I noticed
some small problems in the BSD installer:
1. When using the guided partitioning with entire disk selected, if you
delete the pre-made "/" and create a new one (to make it a
different
size for example). After hitting OK, the installer asks you to
create an Apple boot partition even though one already exists. If I
select yes, I now have two Apple boot partitions.
2. I also noticed that the numbering gets a little out of order if you
don't delete ALL existing partitions first. At some point I ended
up with the numbering starting at 5 or skipping a 3 for example.
3. If the installer fails at some point and I restart it, the DHCP
option comes back with a an error saying it was not able to assign
an IP via DHCP. I can continue without DCHP and the IP address is
pre-configured, however DNS is not.
4. I wasn't able to create a ZFS partition (for example /data). I was
able to add it from the guided partitioning screen, but when it came
time to format and install, I received a mount error and the
installer failed.
Other than that, the powerpc64 install on a Apple Mac Pro G5 was
successful.
