Disk partition not removed from fstab after deleting partition

[spike]

One of the disks in my machine had two partitions on it. A test install of MINT on ext4 and a swap partition (machine was original dual botted).

The ext4 partition was mounted via /etc/fstab on startup. I deleted both partitions and re-partitioned the disk with a single ext4 partition using the GUI tool:

gnome-disk-utility 3.18.3.1
UDisks 2.1.7 (built against 2.1.6)

When I rebooted the machine it failed to boot complaining of TOCBLOCK database corrupt. All I could get was a command line.

Took me a few hours to work out the problem was that the partition was mentioned in /etc/fstab.

I'd have expected that the disk utility would have tidied that up when the original partition was deleted.

This does kind of relate to #1458474. Although the cause is different (and in my case I'd argue the utility should handle it) the mitigation is probably the same, allow the machine to Skip the mount of not found or problem disks.

Running Mint 18.1, cinnamon 64 bit.
