Hi Clément,

Looking at ‘invoke-action’ (used by ‘start-service’) in (gnu services
herd), it seems that an exception is raised upon error:
(('reply ('version 0 x ...) ('result y) ('error error)
('messages messages))
(for-each display-message messages)
(raise-shepherd-error error)
#f)
There’s one case where an exception isn’t raised, and that’s when
shepherd returns something completely bogus:
(x
;; invalid reply
#f)
Am I missing something?
Thanks,
Ludo’.
