I have an Ubuntu 12.04 server at home. It was working fine utile yesterday when I did an apt-get upgrade.
First problem : grub timeout is disabled. Bootup hangs on grub.
Second problem : the services configured to startup on the defaults runlevels wont start (Apache2, transmission-deamon, sambad, etc).
Here is a dump of my boot.log file
root@HomeServer:~# cat /var/log/boot.log

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service S20dovecot start
initctl: Unknown job: S20dovecot
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start S20dovecot
