Comment:
So, I gave this a try and didn't encounter any xbps-alternative bugs. However there is an issue when trying to shutdown with runit after switching the alternative to s6, because `poweroff-runit` doesn't work as is:
1) It should be a symlink to halt-runit instead of halt
2) halt-runit should be instructed to reboot/poweroff when invoked through reboot/poweroff-runit
