[Message part 3 (text/plain, inline)]

the facts:
----------

start GEXP's of services are loaded into unnamed modules. the definitions from (shepherd support) are visible in these unnamed modules. see the attached rerpoducer.

it can be run with:

$(guix system --no-graphic vm reproducer.scm)

and in the VM (must use fold, because it's a dumb terminal):

cat /var/log/messages | fold -150

and observe that (shepherd support) is listed.


questions:
----------

is this indended? i.e. part of the shepherd API?

if not, then this is probably a bug. looking at the public definitions in (shepherd support), it's not obvious that those are meant to be available for the users of shepherd. either way, this should probably be documented with at least a comment at the top of the file.

if this is intended, then where is this module imported? i looked all around, and i can't seem to find what mechanism imports this support module into the unnamed module that are used for the GEXPs.


my ultimate issue:
------------------

my service code has conflicting definitions with (shepherd support), and i need to know the intent in the shepherd API to decide on the proper fix.
