You can see that on line 1020 "user-processes" successfully starts, but "guix-daemon" or "nscd" doesn't attempt to start afterwards for some unknown reason. Below is a summary of the relevant events from the log: 1 - System starts booting 873 - "user-processes" service fails to start 908 - "user-processes" service fails to start a 2nd time 910 - "nscd" service fails to start 920 - "user-processes" service fails to start a 3rd time 922 - "guix-daemon" service fails to start 943 - "user-processes" service fails to start a 4th time 1020 - "user-processes" service starts successfully 1071 - "ntpd" service starts successfully 1075 - "mcron" service starts successfully This seems to indicate that the Shepherd will attempt to start "user-processes" multiple times until it succeeds. But Shepherd won't try to start "guix-daemon" or "nscd" if it has failed once. Cheers Markus
