This is something that is not easy to reproduce, but working in a gnome-control-center fork that shows password-hint in the password dialog (calling act_user_get_password_hint() ), sometimes instead the user real name is returned instead. Taking a look at the code, this happens when _act_user_load_from_user() is invoked. Turns out that in this code, we get rid of the old user password-hint, and instead of using the password-hint of the new user, we use it's real name. I don't know if this is done on purpose (due some sort of security problem), or is rather a bug, because as far as I understand "user" and "user_to_copy" are the actually the same user. So copying the password-hint value shouldn't be a problem.

yea clearly just a bug, not by design

Created attachment 114096 [details] [review] systemd: make sure to only start plymouth is started This commit makes sure gdm doesn't start in parallel with plymouth, which could lead to plymouth activating after X is started. Furthermore, GDM is replacing getty@tty1.service and plymouth-quit.service, so it needs to have the same dependencies as them.
(ignore that last patch, wrong bug)
