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. > 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. 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. Stroller.
