I propose to add new option "presubj" to dh_runit. With this option,
dh_runit should install file into /usr/share/bug, so when user is about
to report a bug in a package with reportbug(1), he will be shown notice,
that if bug is in runit integration, he should add runit mailing list
into CC, to relieve burden from maintainer of service, who unlikely
to use runit init system himself.
