Does this link work for anybody else?

This link should be How to enable the (new) GUI VM? - #3 by marmarek.

Gentoo-template is using OpenRC as init, so Alpine-template is be able to made, Alpine is using OpenRC too.

In other words, Qubes-builder tools for OpenRC are already existing, so Using OpenRC template can make.
So if I use it, for example I can make Artix-template. Artix use OpenRC as init too.
In that case, is Qubes-builder be able to use to make for using SysVinit or Runit template?
For example VOID and antiX are using Runit as init, Slackware and MX and PCLinuxOS and Devuan are using SysVinit as init.
I can Artix-template using Qubes-builder, Qubes-builder is supporting to OpenRC.
But If Qubes-builder tools are not supporting to Runit and SysVinit, if I hope to make VOID or PCLinuxOS template, I must start from make Qubes-builder tools for Runit or SysVinit.

I hope to know if Qubes-builder is supporting to Runit or SysVinit.
In short, is Qubes-builder for init neither systemd nor OpenRC?
