Description of problem:

Default, installed configuration file, /etc/inadyn-mt.conf contains 'background' command which is incompatible with systemd -- as a result, the command, 'systemctl start inadyn-mt.service' fails to start service.  Since there is no init script installed for deprecated startup compatibility, the config file should not contain the background command.

Version-Release number of selected component (if applicable):

inadyn-mt.v.02.18.36

How reproducible:

Edit default installed configuration file according to dynamic dns system requirements, but do not remove background command option.  Attempt to start inadyn-mt.service.  Issue systemctl status command to view failed start status.

Steps to Reproduce:

1.  See that /etc/inadyn-mt.conf configuration file contains single line command
option, 'background'.

2.  Attempt to start service with systemctl command.

3.  Check service status with systemctl command.
  
Actual results:

Service status check returns:

Loaded: loaded (/lib/systemd/system/inadyn-mt.service)
Active: inactive (dead)
Exited: 2019 (/usr/sbin/inadyn, code=exited, status=0)
CGroup: name=systemd:/systemd-1/inadyn-mt.service

Expected results:

Loaded: loaded (/lib/systemd/system/inadyn-mt.service)
Active: active (running)
Main:   2027 (inadyn)
CGroup: name=systemd:/systemd-1/inadyn-mt.service
        └ 2027 /usr/sbin/inadyn
