It is _not_ caused by the initrd per se, I have just rebooted the system
and edited the grub commands to load the .broken initrd, and it came up
fine.
I will make a snapshot in the broken state the next time it happens,
maybe something else is broken. Except for update-initramfs I did not
run any command, but the system was fully booted on the Wheezy kernel,
maybe something else triggered a fix.
I hope to upgrade a few more systems today, maybe I can reproduce it.
Best Regards,
Bernhard
