Can not log in with root anymore

Hi there,
I installed NixOS and then added a user account and now it seems that I am not able to login with root anymore. I did not really bother to remember the password I set for the user I created because I thought I will be able to login with root anyway.
Why is it now not possible to login with root anymore?
Best regards

Take a look at the users.mutableUsers option here: NixOS Search

According to the documentation:

If set to false , the contents of the user and group files will simply be replaced on system activation. This also holds for the user passwords; all changed passwords will be reset according to the users.users configuration on activation.

Perhaps the above corresponds to your situation.

Probably…I assumed root will not be affected but it is clearly stated that the whole file will be replaced :cry:
