I've performed a manual compile of gentoo-dev-sources-2.6.3-r1 and when booting I get,

You probably forgot a kernel option or two. Make sure you have both proc and dev filesystems compiled into the kernel, and set to mount at boot time.

I ran into a similar (but not exacly the same) issue, where i got complaints about not being able to open an initial console.

I moved a system over to a new disk array. i was told that I didn't have to copy over /dev/ , as long as I had devfs mounted at boot.

When I booted I got the error about unable to open an initial console.

Turns out that no matter what, in /dev/, you must have at minimum /dev/console and /dev/null . Be sure and use rsync -avD to copy them, or else they won't be created properly.

Let me know what happens, it worked for me.

Hehe. I like the Location: in your profile.

Anyway, none of that will matter if you don't have /dev/null and /dev/console . If /dev/ is empty, you will not get an initial console, and the machine will reboot.

Looks like we post back and forth too fast.

rsync is similar to cp, but a lot more powerful. rsync is what portage uses to sync up it's tree, which is why it's called emerge rsync or emerge sync.

What I would do is boot the livecd, mount you root gentoo partition at say /mnt/gentoo/ , and then rsync -avD /dev/{console,null} /mnt/gentoo/dev/ . Be sure and check /mnt/gentoo/dev , and make sure console and null are there, and not another dev directory. You might need to take off the trailing / at the end of the rsync command.

I guess that blows my idea away, darn. But it's still something good to know on a devfs system.

Hope it works out for you.

What architecture do you have? I seem to remember something about amd64's needing an initrd, which could potentially be your issue.
