Package: runit
Version: 2.1.2-3
Severity: wishlist

Dear Maintainer,
When running a process who fork itself with runsv, like haproxy, it
detach from it's parent and is adopted by init (pid 1).
In some situations, when running in isolated environments like
docker / mesos-executor, or just to keep the process tree readable (ps
afx), it'll be better if runsv could adopt it's orphaned children.
Linux is providing since kernel 3.4 a subreaper feature, the following
patch enable this feature when available.
