I'm afraid the last update on a server I run has made it not able to run init scripts after "Booting (initramfs)". The kernel was upgraded to 3.5.0 at the time the damage was done, I've since upgraded to 3.6.0 from a livecd but it wasn't repaired by that.
It's an LVM JBOD setup with a non lvm boot partition. I pursued grub issues for a while and managed to remove some file not found errors. I get an mdadm error saying missing arrays but I never set up anyway.
In rescue mode the system gets as far as starting init scripts and then returns the error cannot execute /etc/init.d/rcS
enter root password for maintenance. None of the init sripts have run, no network or anything.
From a live Cd I've removed some old kernels and reinstalled openrc and udev for the hell of it to no avail.
From the live cd I chrooted with the boot partition mounted in the right place before any kernel or grub changes.
fsck was clean on the volumes
Lost for options right now, any ideas?
