Hi all,

Thanks for the info. I like the way user shepherd services work so far. I haven’t used it much yet but it seems to mostly do the trick. The only thing I want is the declarative configuration. By “declarative” I mean configured in config.scm. Do you think there could be a chance of adding a services field to the user record type to create a corresponding Shepherd init.scm for user level shepherd services?
