[Nut-upsdev] Systemd sequencing problem in Fedora 16,17

[Stuart D Gathman]

I am running nut in Fedora 17 (previously 16).  There is a bug in
startup that I think I understand well enough to explain.  The symptom
is that upsd refuses to start at boot time, complaining:

Oct 12 22:28:22 melissa upsdrvctl[868]: Network UPS Tools - UPS driver 
controller 2.6.5
Oct 12 22:28:22 melissa bestfortress[937]: Startup successful

file or directory

Oct 12 22:28:22 melissa upsd[938]: listening on 127.0.0.1 port 3493
Oct 12 22:28:22 melissa upsd[938]: no listening interface available

That is the correct IP6 address - it just hasn't been initialized yet.
When booting is complete, I start it up manually with "systemd start
nut-server.service":

Putting the systemd start in /etc/rc.d/rc.local is still too soon.  It
takes a few seconds for dhclient -6 to pick up the IP address.  I am
able to work around it with this in rc.local:

at now + 1 min <<EOF
systemctl start nut-server.service
EOF
