I'd like to be able to get hotfixes for haproxy like in #354713 without writing additional ebuilds. Thus I've created a live ebuild. It's possible to use it as haproxy-1.4.11-r1.ebuild and haproxy-9999.ebuild, it will determine if it's a live build or not. When the versioned ebuild is changed, we will just have to cp it to haproxy-9999.ebuild easing ebuild management. I am not sure if it is neccessary to do a revbump because I did not add/change anything except for the git part.
Created attachment 263655 [details, diff] haproxy-9999.patch
I don't think we'll need a live ebuild anymore. If there are important patches just file a bug and I'll add it.
