Well, this should test if the database is encrypted but currently it is
still unencrypted and we need to notice if this behaviour changes in the
future (as it will cause data loss, see e.g. #108772).
Anyway, this doesn't really matter for security reasons but we need this
test to prevent data loss (unfortunately Signal-Desktop and SQLCipher
handle this badly... :o).
This module allows root autoLogin, so we would break that for users, but
they shouldn't be using it anyways. This gives the impression like auto
is some special display manager, when it's just lightdm and special pam
rules to allow root autoLogin. It was created for NixOS's testing
so I believe this is where it belongs.
