Hello,

Danny Milosavljevic <dannym <at> scratchpost.org> skribis:

> But gnu/services/shepherd.scm shepherd-service-file could be extended to provide a "restart" action (shepherd itself already supports it).

> But the Guix <shepherd-service> record, which is the source that is eventually compiled to the above, neither has an "actions" slot nor a "restart" slot.  It would have to be extended with one.

Not yet, but it should.  I think the patches at
<https://bugs.gnu.org/26830> would be sufficient if the action boils
down to sending SIGHUP.  Perhaps time to revive that patch set!
