    I could certainly see how this could be done - but it would require persistent filesystem snapshots. The obvious method would be LVM snapshots (although I am personally not an LVM fan.)

    Something along the lines of:

    > OS is running - snapshot is created (manually or automated.)
    > Updates are applied and filesystem is changed.
    > Upon normal reboot, OS doesn't boot.
    > Reboot again - a GRUB option was previously added that boots a very basic kernel/shell. The shell gives a menu - here are the snapshots available - do you want to rollback to one? User selects a time before update and filesystem is reverted to snapshot.
    > System reboots - now the normal GRUB option will boot successfully.
