Hello,

My remark was in the context of booting, where a service depends always
on some #:requirement (file systems mounted, udev present etc...),
and transitiveley to an ultimate ancestor (which #:requirement
I force to be root, may be this isn't necessary)

If you run shepherd for user services, it makes sense to have
#:requirement empty.

It would perhaps make everyone happy to add the root service in the
graph only if #:requirement is empty.
