[arch-general] Arch Linux and systemd

For now, this only seems to work for starting, stopping and reloading 
services. Unfortunately it doesn't yet seem to work for enabling or 
disabling them. If I try for example

sudo systemctl enable netcfg at Kyle

or

sudo systemctl disable netcfg at Kyle

I receive the following error:

Failed to issue method call: Invalid argument

If I use the .service suffix, it works as expected.

sudo systemctl start netcfg at Kyle

and

systemctl stop netcfg at Kyle

also work as expected. Maybe it's a bug, but for now, I'll just remember 
the .service suffix unless I find out this behaviour is indeed abnormal. 
Thanks for the link. The wiki page is well written and helped prevent 
some potentially major headaches.
