Thanks for correcting me, i mixed it up a bit. But after looking in into the init-system I found the problem (or at least I fixed it).

Since the init did not work I tried:
# openrc sysinit

and got some errors I can not fully recall. So I took a look at dmesg (needed to use the command, since the file did not get created) I saw: the problem was a segfault in libselinux. I switched to the live-cd mounted all partitions chrooted in it, then I reemerged the whole system (emerge -ae world), because I wanted to be sure to go safe. After this I double checked the kernel configuration again and rebuild it as well (the same with the initramfs). This solved the problem, at least for me (finally I have the right keyboardlayout loaded on boot ;-).

Thanks for all your help pointing me in the right direction (especially with /proc/mounts which cleared the way). I learned quite a lot and got my system running the I want.
