restarting services

Bug description:
I got today the same problem in 2 servers.
In one of they the problem was nginx and on the other server was
proftpd.
I didn't touched any config on both servers, I simply tried to start
the services another time and it worked, so I think it's a network or
DNS related problem.
I think needrestart should have a list of processes (we will call they
'first to restart' services) which can affect the restart of other
services. Priorize the restart of those 'first to restart services'
and wait for network and DNS before restarting other services which
need to be restarted.
IMHO those 'first to restart' services should be, on this report
scenario, the services systemd-networkd.service and systemd-
resolved.service.
Let's check the logs:
Those are the services needrestart restarted and I got one error on
nginx.
---------------------------------
Restarting services...
/etc/needrestart/restart.d/systemd-manager
systemctl restart nginx.service packagekit.service ssh.service
systemd-journald.service systemd-networkd.service systemd-resolved.service
systemd-udevd.service udisks2.service
Job for nginx.service failed because the control process exited with error
code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for
details.
Service restarts being deferred:
systemctl restart systemd-logind.service
systemctl restart user@1000.service
---------------------------------
Checking the log I see the failure when needrestart tried to do this
job, and the next block of the log shows my manual start of the
service just before the failure.
