Today I did a world update on my ~amd64 gentoo box and noticed that it updated systemd as well. I've already migrated to systemd succesfully months ago and have had no problems with it so far, but after rebooting my box I am finding that the kernel fails to execute systemd (with init path set to "/usr/lib/systemd/systemd") for some reason and panics (screendump at http://i.imgur.com/NXpU7Xv.jpg)

Is this a known issue, or if not, does anyone know what might cause this or how I can go about fixing this? Afaict my init path is set correctly on the cmdline, and I can only assume the systemd binary is still present at that location. My /usr is on my rootfs.

UPDATE: Booted my 'unbootable' system from a fedora liveusb stick I still had, the binary is definitely still there. For shits and giggles I tried to run it and it complained about a missing shared lib (libseccomp.so.2), but I guess that may be normal since I'm trying to run it from Fedora. Not really sure how to proceed now though..

chroot to the system partition. then you can try downgrading if possible or just reemerge it and also check if the ebuild wants you to do some change to the system.

I figured it out.. I left a USB stick in, which changed my rootfs' /dev path, but since the USB stick apparently had a mountable fs on it, the kernel didn't panic with the usual 'failed to mount root' and I assumed it had something to do with the systemd update I just did...

I should really start using UUIDs.. sheesh

Sorry for the noise and thanks for your reply!
