FTR, I had used 'guix deploy' and issued 'sudo herd restart guix-daemon' on the remote after it completed successfully. Why should stop + start be different than restart though? That seems counter-intuitive. > Note that the guix-daemon process you should seems to be a child process > (presumably because there was still a client running when you restarted > the service), not the main guix-daemon process. > > You should check the command line of the main process, the one returned > by “herd status guix-daemon”. You are right that this process has the correct arguments: $ sudo herd status guix-daemon Status of guix-daemon: It is started. Running value is 25628. It is enabled. Provides (guix-daemon). Requires (user-processes). Conflicts with (). Will be respawned. $ cat /proc/25628/cmdline /gnu/store/rqif4yxa6ny4nxrdq6whnva2r089jm0c-guix-1.2.0-13.a53f711/bin/guix-daemon--build-users-groupguixbuild--max-silent-time0--timeout0--log-compressionnone--discover=no--substitute-urlshttps://ci.guix.gnu.org--max-jobs=20 Some of the other process were apparently caused by 'guix environment' shells still running in screen; I've terminated them all now and ran 'sudo herd stop guix-daemon'; surprisingly I still had two remaining guix-daemon processes that were launched manually for testing purposes. That's on a Guix system with an uptime of 174 days and counting :-). Thank you for the answer and sorry for the noise! It works as designed. Closing. Maxim
