Add information about disk encryption to setup dialog
In https://forums.puri.sm/t/understanding-the-pureos-default-disk-encryption-luks-cryptsetup-possible-security-issue/6772/4 I described how I found more or less accidently that the key to my encrypted disk in preinstalled PureOS on a Librem Notebook wasn't set during inital setup by myself, but traveled all the way from Purism to my desk unprotected and I only set a password to protect the former unprotected masterkey for disk encryption.
I also wrote down the steps I took to re-encrypt the disk and thereby change the masterkey.
In my opinion the user has to be informed that the password set during initial setup is not the encryption key for the disk, but only protects the already set encryption key in future. There should be a reference to some explanation about the background, which risks are involved changing the encryption key and which risks the user takes in not changing it.
