Can confirm.
Activation script tries to load latest shepherd configuration with `herd
load root ./path/to/config.scm` and it starts a shepherd process. Login
shell starts the shepherd process as well. Probably we need to do
config reload using on-change service and also not trigger on-change
stuff if user isn't logged in. I can think on the proper solution and
make a patch with a fix later this week or beginning of the next week.
