Starting with Shepherd 0.9.0 and the use of 'make-inetd-constructor' in
commit 808b9e850491c7b1d867a5f1f4d5ee6f61f345d4, systems might be
running transient Shepherd services such as those corresponding to SSH
connections.  Before this change, 'shepherd-service-upgrade' would have
those transient services in the list of services to unload; concretely,
that would lead all SSH connections to be closed upon 'guix system
reconfigure'.

* gnu/services/shepherd.scm (shepherd-service-upgrade): Remove transient
services to TO-UNLOAD.

2022-04-07services: shepherd: Default to version 0.9....* gnu/services/shepherd.scm (scm->go): Define 'shepherd&co' and pass it
to 'with-extensions'.
(shepherd-configuration-file): Call 'start-in-the-background' when it is
defined.
(<shepherd-configuration>)[shepherd]: Default to SHEPHERD-0.9.
* gnu/system.scm (hurd-default-essential-services): Use SHEPHERD-0.8.
