We probably should document how to setup these repos.  I think this is on the old busted wiki. 

Maybe something simple like:
```shell
$ cat > /etc/apt/sources.list.d/holland.list <<EOF
deb http://download.opensuse.org/repositories/home:/holland-backup/xUbuntu_$(lsb_release -sr) ./
EOF
$ curl http://download.opensuse.org/repositories/home:/holland-backup/xUbuntu_$(lsb_release -sr)/Release.key | sudo apt-key add -
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1023  100  1023    0     0   3625      0 --:--:-- --:--:-- --:--:--  7359
OK
```
