Fixed (though there is nothing else in GNUmakefile that uses = y, or in
any Build script, so I'm not sure what you're referring to...)

... oh, you mean in the output of Makeconfig. Makes sense, agreed.

... that's a really stupid description, isn't it! I kept on rephrasing
until I got something that was in <80 and ended up with gibberish.

Simply 'Install the systemd unit files (default: yes)' 45 chars, just
barely fits in 80.

Ack.

I've also arranged that --with-systemd=y* turns it on, and n* turns it
off, entirely so yes and y turn it on, and n and no turn it off :)
