Hi,

no Answer but a question:
What Computer(s) do you want to use it with?

1ghz eMac - the old CRT model, but the eMac is larger (has a larger screen) than the CRT iMac.

I think it's a G4, it's 32-bit.

Tentatively speaking, I think I'm on the right track, actually.

Having made a final second-guessing-myself attempt with Finnix, it seems like the yabootconfig isn't working, but it looks like it's gonna boot using the manual Yaboot configuration. IMO this is explained a little poorly in the docs (but it is a niche arch, so I'm not complaining).

I hadn't posted back before because it looks like yaboot doesn't support ext3, so I'm now having to go back and make a separate /boot partition. 

I believe this is my first time installing on PPC - I may have done it before, but if so I remember none of the details - and the quirks are all a bit unfamiliar to me.

I boot my G5 late 2005 from ext4 with yaboot: 
sys-boot/yaboot-static-1.3.16-r1

I don't know anything about G4's, but for me it was, as far as I
remember mandatory to use the static version of yaboot.

(The only useflag "ibm" is set, but probably not necessary)

I use:

This statement caught me just finished dd'ing a filesystem back into the new partition, having rearranged everything and created a 100mb boot partition. So it took me a little while before I could test. Good news: I've got it working, now. Bad news: because I don't need that separate /boot, and to keep things tidy, I'm going to have to undo all my repartitioning before I continue much further.

Ah, I had installed sys-boot/yaboot (I think that's what the manual suggested) and it has now started booting from my ext4 filesystem.

I saw a message about being unable to load VFS, about sda5 not being found, and then something about "hd:" repeated a few times.

I commented / changed my yaboot.com thusly:

  image=/boot/vmlinux-3.5.7-gentoo
    label=Linux
    #root=/dev/sda5
    root=/dev/hda5
    partition=5
    read-only

ran `ybin -v` and, on reboot, it worked!

I find it a little strange to be using "hdX" rather than "sdX" now, but I think that's it sorted. 

It also seems strange that yaboot and yaboot-static differ in this syntax, but I don't care enough to investigate.

Ooops. Looks like it might be my kernel that's causing this.
