Script to add all the partitions to the fstab.

bash Fedora

I wrote a simple script today to get all the partitions on all the disks and then create <a class="zem_slink freebase/en/fstab" title="Fstab" rel="wikipedia" href="http://en.wikipedia.org/wiki/Fstab">fstab entry with them. The script also gets the <a class="zem_slink freebase/en/universally_unique_identifier" title="Universally Unique Identifier" rel="wikipedia" href="http://en.wikipedia.org/wiki/Universally_Unique_Identifier">UUID and uses the same to make the entry 🙂
