ifupdown 8.8 real slow startup

[paxmark1]

I had a huge puzzle in Sid, why is lightdm coming online faster than my network.  I was going to tty1 after logging in and systemd was still chugging along

From the debian changelog of ifupdown

http://metadata.ftp-master.debian.org/changelogs/main/i/ifupdown/ifupdown_0.8.10_changelog

ifupdown (0.8.9) unstable; urgency=medium

  * It's network-online.target, not .service.
  * Do not run "ip link set down" on manual interfaces during "ifdown -a".
    Closes: #809166
  * Add the keywords "no-auto-down" and "no-scripts". Closes: #615130

search engines are not great for non-existing services, ha ha. 

Also adding to the mix was the change in 8.7

Impose a 5 minute timeout for starting network services.
    Closes: #318577, #810656

So, if it is taking forever  ("systemd-analyze blame"  is your friend here to identify) - well it is mostly harmless and will be upgraded soon.   

Lot of juggling going on with ifupdown taking some things away from systemd in Debian (and probably ubuntu also)
