bug#48974: A possible shepherd bug (it's very minor)

[Joshua Branson via Bug reports for GNU Guix <bug-guix@gnu.org>]

Hello!

I've had this issue every since I enabled automatic login on my guix
system like so:

#+BEGIN_SRC scheme
(define %my-desktop-services
  (modify-services
      %desktop-services 
    (mingetty-service-type config =>
                           (mingetty-configuration
                            (inherit config)
                            ;;auto login as joshua
                            (auto-login "joshua")))))

(operating-system
   ...
   (services (list %my-desktop-services)))
#+END_SRC

This is the "error message"

#+BEGIN_SRC sh
This is the GNU system.  Welcome
dobby login: joshua (automatic login)
This is the GNU operating system, welcome!

Cannot make/remove an entry for the specified session
#+END_SRC

Essentially, mingetty tries to auto log me in, but I am using desktop
services.  So mingetty tries to log me in, before many of the desktop
services are started.  However, I guess this doesn't work.  Meaning,
my autostart sway script is NOT run, until AFTER all of the desktop
services are started.  WHICH IS PROBABLY A GOOD IDEA.  I would rather
log in, when my desktop services have started, not before.

BUT the minor issue is that after I log in, =users= reports:

#+BEGIN_SRC sh
joshua@dobby ~> users
joshua joshua joshua joshua joshua joshua
#+END_SRC

So it looks like 6 versions of myself are logged in by the time I am
officially logged in and I auto start sway via .bash_profile:

#+BEGING_SRC sh
# Honor per-interactive-shell startup file
if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

# shepherd

if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
    export MOZ_ENABLE_WAYLAND=1
    export GUIX_PACKAGE_PATH=/home/joshua/prog/gnu/guix/guix-packages/
    XDG_DATA_DIRS=/var/lib/flatpak/exports/share:/home/joshua/.local/share/flatpak/exports/share:$XDG_DATA_DIRS
    # this may fix a bug that I have with termite confusing backspace as space in guix environment
    # export TERM=linux
    shepherd -c /home/joshua/.config/shepherd/init.scm &
    exec dbus-run-session sway
fi
#+END_SRC 


I'm guessing the root cause is that the shepherd starts most services
sequentially at the moment.  Anyway, I thought I'd share a minor issue
with you all!


Thanks!
