Sounds impossible. I mean, the ‘stop’ method of ‘root-file-system’ could throw an exception and not do all its work, but it’s necessarily reached or we’d never call reboot(2).

That's ok--but good to know) Not random: see ‘herd status log-rotation’ and this: https://www.gnu.org/software/shepherd/manual/html_node/Log-Rotation-Service.html :-) HTH, Ludo’.
