Subject: [PATCH 138/198] Warn if grub password will not be read (#1290803)
It is possible for a system to have never run grub-mkconfig and add the
section that reads the user.cfg file which contains a user set GRUB
password. Users in that scenario will now be warned that grub-mkconfig
must be run prior to their newly set password taking effect.
Resolves: rhbz#1290803
