Thanks! The order has already been corrected in #1338, which will be merged soon.

@chrysle my bad, I'll remove the parameter fix, but will leave only the Arch addition then.

Please add a changelog entry as well.

Should it be added to the changelog even tho it doesn't affect the end users? I don't see a reason to flood the changelog just for adding a new instruction for a distro
