Keeping it up to date

Since Ubuntu is based on debian, keeping it up to date is as simple as running:

apt-get update
apt-get upgrade

Notes

This filesystem will not boot to a login prompt when used with UML.
Plymouth should be disabled and /dev should be mounted by the fstab as per these instructions
That's still not enough to make it boot to a prompt... so maybe these will be useful:
* debugging startup problems on Ubuntu
