I installed 10.10 a few days ago. The only changes to the default install are the addition of Chrome and Pinta.
It was fine for a few days, then today login etc seemed slow. Likewise it couldn't even render the restart/shutdown menus.
Hoping it was some botched update, I ran the update manager; it tried to install but failed (the UI didn't make it obvious what had failed).
Fine, ok. Shut it down (press enter on the blank shut-down dialog).
Fire it up hoping... And... #fail.
Target filesystem doesn't have requested /sbin/init. No init found. Try passing init= bootarg.
Is it now a brick?

udevadm trigger is not permitted while udev is unxonfigured Giving up waiting for root device.

mount: mounting /dev on /root/dev failed: No such file or directory
Then the same for /sys and /process
