Last month, Shepherd integration in Guix was fixed so that failure to
load one service would not prevent the system from loading and starting
other services:
https://issues.guix.gnu.org/71144
Does the problem still manifest on a system reconfigured from a commit
after cca25a67693bb68a1884a081b415a43fad1e8641?
(See also <https://issues.guix.gnu.org/71193> for a recent example in
that vein and how the change above addresses it.)
HTH,
Ludo’.
