I am also encountering the problem that the system won't boot after the update. Tried it on two different Model B raspis, with three different SD cards of which two were clean installs with 1.0a5. Tried updating via SSH, even gave it a try via the Xbian Config. I've been going through the update process at least five times on both of the machines with different setups, wasn't successful even once. I suggest rolling back the update ASAP, since even clean installs won't work until there's a fix...

Edit: The nightly-workaround that highway suggests seems to be working...
