Public bug reported:
Binary package hint: upstart
"telinit 1" causes a hang. The root shell prompt never appears. The
screen is left showing the boot/shutdown splash.
To reproduce:
1. Log into a Gnome Classic (no acceleration) session.
Make sure root has a valid password (run 'sudo passwd root')
2. Ctl-Alt-F1 to switch to a VT (in VirtualBox, press HostKey+F1)
3. In the VT, log in as root
4. telinit 1
Results:
The purple "Ubuntu" boot/shutdown splash screen appears, the dots advance for a
while, then stop with all dots white.
Nothing else happens.
I suspect that the upstart scripts are forgetting to remove the shutdown
spash screen, and so I can't see the console prompt (just a guess).
NOTE: I'm running in a VirtualBox VM. I need to enter single-user
mode to remount the root fs read-only, to prepare to run "zerofree"
(which zeroes unused blocks, allowing the VM's disk image file to be
compressed during backups...)
