I am using GNOME 3 on NixOS 16.09, and I cannot figure out how to make the Login keyring unlock automatically on login.I suspect this could be fixed with the security.pam.services option, but I am not an expert, and the documentation is not very verbose or clear:This option defines the PAM services. A service typically corresponds to a program that uses PAM, e.g. login or passwd.  Each attribute of this set defines a PAM service, with the attribute name defining the name of the service.Type: list or attribute set of submodulesDefault: [ ]A related but less important issue is that if I create a new user account under NixOS and log in with GNOME, no keyring is automatically created.  The first time I enter a password somewhere and accept to save it in a keyring, I get a dialogue asking for a password to create a new default keyring:Choose password for new keyringAn application wants to create new keyring called 'Default keyring'.  Choose  the password you want to use for it.Note that it wants to create a keyring called Default keyring, and not Login, like Ubuntu does.If I type in my login password, the keyring is created, but on the next login it is not unlocked automatically, and I am asked for a password the first time I try to use it.Here is an analogous question about KDE Wallet, which so far has no accepted answer.There is a relevant issue reported for Nixpkgs.
