IMPORTANT: this change has a docs/UPDATING entry! This rename is unfortunately necessary because NetBSD has decided to create its own service(8) utility, and we will want to import theirs as well. The two can obviously not coexist. Also move ours from /bin to /sbin, as it is a superuser-only utility. Change-Id: Ic6e46ffb3a84b4747d2fdcb0d74e62dbea065039
