bug#36221: Make GDM *not* restart 504 times on failure

[pelzflorian (Florian Pelz)]

If GDM does not start for whatever reason, it attempts to restart 504
more times which all fail and overwrite all five old logs.  It
probably should not attempt to restart at all.

I think the auto-restart code that’s triggered is in GDM itself, no?

Yes, you are right, I did not expect that.  GDM gets stuck in a
not-quite-endless loop of recreating its seat after Xorg failures, in
gdm-3.28.2/daemon/gdm-local-display-factory.c in “case
GDM_DISPLAY_FINISHED”, until after some 505 repetitions recreation
fails due to “WARNING **: 20:41:01.908: Could not start command
'/gnu/store/2sh9nh36fdh2k6l65q24154c2czq1v57-gdm-3.28.2/libexec/gdm-session-worker':
Too many open files”.  I will investigate further if this happens on
newer GNOME and other distros as well.

This is not a Guix bug.  Closing.

Very many GDM restarts is what happens on Debian Stretch and Arch
(GNOME 3.32) as well after renaming /usr/share/xorg/modules, just like
it does on Guix.  On Guix’ wip-gnome3.30 GDM fails in a different way;
maybe I will investigate further and then file a bug at GDM.

Thanks for checking!
