[Bug 1485708] Re: fstab entry causes emergency mode to come up

[WhyteHorse]

I already upgraded so I just have to use recall at this point. From a
user's perspective, it would be useful to know why the system dropped to
a shell. Perhaps an error message that says "bad entry in /etc/fstab on
line 5" or something like that.

Title:
  fstab entry causes emergency mode to come up

Status in mountall package in Ubuntu:
  Incomplete

Bug description:
  After upgrading from 14.04 to 14.10 and also from 14.10 to 15.04, the system goes into emergency mode when there is an entry in the /etc/fstab file for a <removable> hard drive that isn't connected. Here's the fstab file that caused it and the HITACHI entry has been commented out which fixed the problem.
  # /etc/fstab: static file system information.
  #
  # Use 'blkid' to print the universally unique identifier for a
  # device; this may be used with UUID= as a more robust way to name devices
  # that works even if disks are added and removed. See fstab(5).
  #
  # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  # / was on /dev/sdb2 during installation
