I'm using Fedora release 23 (Twenty Three) and Apache/2.4.23 (Fedora)
I notice that apache 2.4 has -DFOREGROUND as default when starting:
/usr/sbin/httpd -DFOREGROUND
I don't want the -DFOREGROUND, for apache 2.2 that I previously used, it has
/usr/sbin/httpd -k start
and thats what I want. so I modified the httpd.service:
# ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND # default in apache 2.4
ExecStart=/usr/sbin/httpd $OPTIONS -k start # this is what I want and in the previous machine that has apache 2.2
but after the change, after "systemctl daemon-reload" and "service httpd start", the httpd status shows inactive (dead):

I'm so confused, apache document has so little about what is DFOREGROUND and what other options I have, how can I stop using this DFOREGROUND?
