Create a networking service script, so we can run it after switchd Ticket: CM-8790 Reviewed By: wkok,roopa Testing Done: built, installed, rebooted jessie's networking starts as an init.d service. Trying to force ordering between init.d and systemd services when there are dependencies doesn't work well (especially since the init.d/networking service is forced very early because of the remote filesystem requirement in jesie). Converting networking to a script run as a systemd service allows us to start networking after switchd. The new script is /sbin/start-networking. I chose to keep it in /sbin, rather than put it in /usr/cumulus/bin, because it's core functionaity. I am not removing /etc/init.d/networking, it just gets ignored unless somebody types it manually. If somebody does that, systemctl runs through the lsb hooks. The two lost abilities below are just ignored if passed. I'm also preventing creating the rc.d symlinks to the init.d/networking script to reduce future confusion. We lose some init.d "convenience" functionality because it's not available through systemd. What we lose are: reload-currently-up - can still be done with ifreload --currently-up force-reload - can still be done with ifreload -f -a We keep start, stop, reload, restart

Fixed one more reference to /etc/init.d/networking; remove switchd dependency Ticket: Reviewed By: trivial Testing Done: built, installed Don't want to leave incorrect confusing references behind. Instead of having the networking script depend on switchd, since ifupdown2 is upstream, I'll add the reverse dependency to the switchd.service. Added Documentation line
