With OpenSSH turned into inetd style in commit 808b9e850491c7b1d867a5f1f4d5ee6f61f345d4, the service upgrade code used by ‘guix system reconfigure’ and ‘guix deploy’ wrongfully decides that the ‘sshd-*’ transient services corresponding to individual SSH connections should be closed:
--8<---------------cut here---------------start------------->8--- $ sudo guix system reconfigure … […] guix system: chargeur d'amorçage correctement installé sur « (/dev/sda) » 0,0 Mo seront téléchargés module-import-compiled 20KiB 1.2MiB/s 00:00 [##################] 100.0% The following derivation will be built: /gnu/store/n99ahnnw94cay1drg499kxsg5ma6598p-upgrade-shepherd-services.scm.drv 0,0 Mo seront téléchargés module-import-compiled 20KiB 1.8MiB/s 00:00 [##################] 100.0% construction de /gnu/store/n99ahnnw94cay1drg499kxsg5ma6598p-upgrade-shepherd-services.scm.drv... shepherd: Removing service 'sshd-1'... shepherd: Service sshd-1 has been stopped. shepherd: Transient service sshd-1 unregistered. shepherd: Done. shepherd: Removing service 'sshd-3'... shepherd: Service sshd-3 has been stopped. shepherd: Transient service sshd-3 unregistered. shepherd: Done. shepherd: Service swap-swap could not be started. shepherd: Service host-name has been started. shepherd: Service user-homes has been started. shepherd: Service sysctl has been started. shepherd: Service host-name has been started. shepherd: Service term-console could not be started. shepherd: Service bluetooth has been started. Pour compléter la mise à jour, lancez « herd restart SERVICE » pour arrêter, mettre à jour et redémarrer tous les services qui n'ont pas été redémarrés automatiquement. Lancez « herd status » pour visualiser la liste des services de votre système. --8<---------------cut here---------------end--------------->8--- I think the solution is to leave transient services untouched. Unfortunately, the status sexp returned by ‘services->sexp’ currently lacks information about whether a service is transient. Ludo’.
