When removing a partition or deleting a partition from partition table , we have to remove mount entry from /etc/fstab if that partition is permanently mounted on the HDA.
Currently we use a fstab gem¹ to manipulate /etc/fstab entries, but it do not provide a mechanism to remove an mount details entry.

Removing an entry from fstab should be done with great attention,unless otherwise whole system will crash in next bootup.
