I installed Ubuntu 14.04 recently.
During the installation I did not create a separate partition for my home folder.
I also accidentally encrypted my home folder.
When i did
I got the result as
Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-root 455G 181G 251G 42% / ....
Why does this have a funny name instead of a normal '/dev/sdx'?
Please explain to me what this is?
