runit-helper/purge_sv funct:
  * add support for multi-intance services foo@default; decide what to do with instances on purge;
  * decide what to do with services in /etc/sv/ (with bin + pkg) when we ship dir=usr
  * decide what to do with user services (maybe needs public discussion)
  * TESTING (lots of)
  * (strictly after testing) open bug to move purge_sv function to an essential package: i-s-h or dpkg (similar to
     rm_conffiles_helpers), or (worst case) make runit-helper essential (needs discussion in debian-devel)

dh_runit:
  * declare the metafiles interface in dh-runit(8)
  * after purge_sv is moved to an essential package: drop runit-helper dep when 'bin=' is in use (#938964)
  * discussion and advise about #1104921 (debian-mentors?)
  * maybe some sugar about milti-instances to track on what the services is instantiating (/dev/? conf file?)
  * (DISTANT FUTURE) drop obsolete options and bump to 3.0 (may require a transition slot)

testrunner.sh:
  * find out if with creating tar before the test changes something (see comment in testrunner.sh)
