Bug Description
The logic in mountall.c forces the system to wait for all mounts within /usr and /var before continuing the boot process. Sometimes, networked filesystems are mounted within these directories.
Because the services that support networked filesystems aren't necessarily started when mountall runs, this can cause the boot process to hang. This has been fixed for Ubuntu 14.04 (mountall 2.53) by allowing the 'nobootwait' flag to be set even for filesystems within /usr and /var, allowing the administrator to specify which filesystems can be ignored.
We only have problems with networked filesystems mounted under /usr and /var; elsewhere they are fine (as the system will skip waiting for them by default).
I'd like to request a backport of the code from 2.53, which permits the use of 'nobootwait' on filesystems under /usr and /var, onto 2.36 for Ubuntu 12.04.
Status changed to 'Confirmed' because the bug affects multiple users.
