My first mistake was trying to use the default btrfs root filesystem.
I quickly realized that yaboot can't boot to btrfs. I then tried to
use an ext4 /boot, but that didn't work either, figuring that it
couldn't find yaboot.conf on the btrfs partition. Then I reinstalled
with ext4 root partition, but it still didn't work. Turns out yaboot
doesn't support ext4 either :( Finally set root to ext3 and everything
went fine. I wonder now if I could have used an ext3 /boot and things
would have been ok with a btrs /. I'm not sure how yaboot would read
the yaboot.conf, however. Can this be put on the /boot?
You can embed config file
into the binary.
It also didn't help that the installer is a bit bugged. Here's the
bugs I encountered, not sure where to file them:
1) After configuring the HTTP installation source, it attempts to
download 5 files. If one of these fail, it continues onward and then
fails with missing files. If you try again, it does not download the
files again, even the ones which failed to finish downloading the
first time. The only way to continue on is to restart the installer.
FTP seemed to work better for me, but not all mirrors support FTP,
especially those that mirror the PPC files.
2) The network setup on build 240 does not correctly set up the
network. I had to configure my ethernet interface manually from a
console. It looks like things work, but when it attempts to download
the files it just gives a generic failure.
3) The network setup doesn't ask for a nameserver anymore, although it
does ask for search domains, strangely enough. I had to look up the ip
address for the mirror and specify it manually. Attempting to set the
nameserver in /etc/resolv.conf didn't seem to work. Testing with curl
gave an error with no route to host for some reason.
I didn't mess with it much, since the IP address was working fine.
please report those bugs to bugzilla? make sure you boot with:
Also there is a DVD media available, but it is not published yet. So
you can download it manually with:
