I wasn't discussing that, but it might be possible to differentiate that
configs and made it possible to for them to share /etc configs between
hosts and make his own
Don't get me wrong, I'm not arguing nor I need this to go in, it just
(still) makes way more sense to me. Take a look at git for example (or
virtually anything) and his /etc/gitconfig => ~/.gitconfig;
$XDG_CONFIG_HOME/git/config => $repository/.git/config and so on...
I've sent a v2 [1] fixing the test.
