bug#22835: Autologin

[Andreas Enge]

Hello,

I am trying to create a configuration using slim-service with autologin.

Looking at the code in gnu/services/xorg.scm, I find the following definition:
(define* (slim-service #:key (slim slim)
                       (allow-empty-passwords? #t) auto-login?
                       (default-user "")
                       (theme %default-slim-theme)
                       (theme-name %default-slim-theme-name)
                       (xauth xauth) (shepherd shepherd) (bash bash)
                       (auto-login-session #~(string-append #$windowmaker
                                                            "/bin/wmaker"))
                       (startx (xorg-start-command)))

The parameter auto-login-session is not documented in guix.texi.

It also is a bit surprising; since I had added only xfce to my packages,
I expected this to start. Or is this impossible to realise?
