It took me three days to identify that a missing loopback line in /etc/network/interfaces was hanging the boot process. The OMGBroken doc is not helpful since upstart doesn't report anything interesting. Even after instrumenting upstart I still don't know what process chokes on the loopback interface; it's not easy to debug upstart.
The failure is completely silent. At the very least, a message could be printed if no loopback interface is present. ** Changed in: mountall (Ubuntu) Status: Invalid => Incomplete -- "initctl emit net-device-up IFACE=lo..." is hanging https://bugs.launchpad.net/bugs/455382 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
