Dh-runit provides a debhelper sequence addon named 'runit' and the dh_runit command.

The dh_runit command installs runscripts and adds the appropriate code to the postinst, prerm and postrm maint scripts to properly enable/disable and purge runscripts. When runit is PID 1 the maint script code also takes care of restarting services during upgrades, when appropriate.
