I was unable to make systemd scripts for Debian 7 and CentOS 6
so for backwards compatability made the SysV script call
/usr/sbin/one-contextd. This should be revisited in the future.
Addded Arch linux support for one-context. Moved the
init.d directory to distro specific directories in
order at add systemd compatability. 00-Network was
also reworked to use systemd-networkd.
