There seems to be two different steps in the Ubuntu Server 14.04 installation that involve encryption. The first asks if I want to encrypt my home directory:
The second has an option for encrypted LVM:
Are these two different encryption procedures? If I do both is my drive doubly encrypted? Why would I do one and not the other?
I don't think this is a duplicate of When installing I'm given the option of encrypting my home folder — what does this do? because that solution does not explain why there are seemingly two encryption steps being offered.
