Well, the use case does vary between machines,

One use-case agnostic reason is because if you don't encrypt your root, someone can modify your binaries in ways you might not notice;

For example, downgrade packages to a version that is vulnerable to an exploit, add backdoors, add applications that can leak your key, etc, etc.

Another reason is sometimes I chain my encryption, for example I'll have a keyfile that is stored on my root partition unlock all the other partitions, to save me from remembering a passphrase per drive, instead I only need to remember one.

But in general, It would be good to be able to live-encrypt my data holding partitions too. If I want to encrypt my 8TB drive array for example, I don't want it to be offline for 4-5 days in the process...

Do you mind if I CC this to the list?

Hi Noah,

I am just curious as to why you would want to encrypt the whole root partition? Would you want to encrypt only home folder or other data holding folder?

Daniel.
