ok, i've attached a stipped down version of the test case. it hopefully reproduces the same situation i'm observing on my servers.

which seems to be the following:

  1. i have a service that keeps respawning (typically due to a config
     mistake)

  2. said service is upgraded/replaced in a `guix system reconfigure`

  3. v1 of the service keeps respawning forever, and there's nothing i
     can do to stop it at this point. `herd disable` operates on v2 of
     the service, while some fiber, or some signal handler of v1 is
     still in a respawn loop.

HTH,
