I installed Ubuntu 16.04 LTS and chose to do full disk encryption as well as home dir encryption.
At startup, I'm asked Please unlock disk sda3_crypt
and I have to manually enter the disk decryption password.
I there a way to auto-mount this, i.e. by specifying the password in the boot script somewhere? (not sure about the right terminology for this) I understand this would nullify any security.
Also, is it possible to retrieve the password from a remote URL, and use that to unlock the disk and continue booting automatically?
Note that I don't want to fully disable disk encryption. I wish to keep the option to re-enable it in the future. Furthermore the retrieve password remotely option (if that's possible) would allow for other possibilities, such as enabling/disabling it remotely, or preventing someone can steal the disk or machine and access it from somewhere else.
