I just ran into a snag with this, because of how Debian formats `/etc/os-release`

<pre>
PRETTY_NAME="Debian GNU/Linux 7.0 (wheezy)"
NAME="Debian GNU/Linux"
VERSION_ID="7.0"
VERSION="7.0 (wheezy)"
ID=debian
ANSI_COLOR="1;31"
HOME_URL="http://www.debian.org/"
SUPPORT_URL="http://www.debian.org/support/"
BUG_REPORT_URL="http://bugs.debian.org/"
</pre>

We can't normalize the value of `NAME` with a regex so this can't be a general solution. I think it could be a fallback mechanism but I really don't want to change the operatingsystem fact on debian to `debiangnulinux`
