My last information about this bug:

- This not only about lightdm, I'm running beta2 and never installed
lightdm, and have the bug

- Something not really installed causes the bug: always at restart we
can see the message "The system need be restarted". Something isn't
correctly configured yet, and will never be...

- Sounds, for me, the problem is caused about a broken link into
/etc/network/run to /run/network (see the bug in last comment). The
folder /run/network and his content is removed at boot for some unknown
application.

- Trying discover what service was removing the folder, I created a script  who executes stop and start for each "initctl list" service list and executed it. The system was automatically restart in some service in that list and all was magically solved o.O'
This make me think it's about some procedure who don't runs at system restart correctily, maybe about a dbus problem (I'm was with a dbus problem who magically disapeared too: "unable to connect to system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: Connection refused") or something more out of my knowledge.

- My problem is out, then I think I cannot bring here good informations.
But something need debug here.

If there are something more I can put here to help, please let me know.

Title:
  Boot hangs at "Booting system without full network configuration..."

Status in “lightdm” package in Ubuntu:
  Confirmed
Status in “netcfg” package in Ubuntu:
  Confirmed

Bug description:
  I installed Ubuntu 11.10 beta1 64bit on a new laptop. I rebooted and
  it came up nicely.

  After that I did "apt-get update" and "apt-get dist-upgrade" to get
  the most recent fixes and installed some additional software.

  Now I do not seem to be able to boot.

  Fist I see:
  Waiting for network configuration...

  Then I see:
  Waiting up to 60 more seconds for network configuration...

  And then it just hangs forever displaying the following:
  Booting system without full network configuration...

  Nothing happens after that, no matter how long I wait. However, I can
  switch to the console with CTRL-ALT-F1 and log in from there. The
  network is configured with DHCP and it works just fine from the
  console. I do not understand what the GUI boot display is waiting for.

  I installed the system using the alternate install CD to get LVM based
  partitions with full disk encryption.

  I noticed the bug #847782 and removed the "auto eth0" entry from my
  /etc/network/interfaces. Unfortunately that did not change anything,
  it still hangs forever.
