Nevermind the last message. I'll put this problem aside until I find the time to solve it on my own.

It doesn't sound as hard as I thought. I'm tired of fighting genkernel. I know the problem is initrd, it's where it fails. Since there is no mkinitcpio package, I'll try those scripts. I will follow https://wiki.gentoo.org/wiki/Early_Userspace_Mounting. If something goes wrong (when I actually try), I'll make a new thread. Or maybe I will just try and copy the initrd and kernel image from the Gentoo recovery pen... Anyway, I'll post here when I figure it out. João Miguel
