bug#53580: shepherd's architecture

[Attila Lendvai]

> Sorry to be direct: is there a concrete bug you’re reporting here?


i didn't pay careful enough attention to report something specific, but one 
thing that pops to mind:

when i'm working on my service code, which is `guix pull`ed in from my channel, 
then after a reconfigure i seem to have to reboot for my new code to get 
activated. a simple `herd restart` on the service didn't seem to be enough. 
i.e. the guile modules that my service code is using did not get reloaded into 
the PID 1 guile.

keep in mind that this is a non-trivial service that e.g. spawns a long-lived 
fiber to talk to the daemon through its stdio while the daemon is running. IOW, 
its start GEXP is not just a simple forkexec, but something more complex that 
uses functions from guile modules that should be reloaded into PID 1 when the 
new version of the service is to be started.
