First of all this is for the rpmfusion list and was off topic for this 
thread that said...

Here is a vboxweb.service that should work for if not you can read the 
systemd man pages and figure out the rest.

### vboxweb.service ###

[Unit]
Description=VirtualBox OSE Web Service
After=network.target

[Service]
Type=forking
PIDFile=/run/vboxweb.pid
ExecStart=/usr/bin/vboxwebsrv --pidfile /run/vboxweb.pid  --background

[Install]
WantedBy=multi-user.target

"/etc/sysconfig/$SERVICE" was dropped since...

a) it does not exist in the package spec file

b) upstream wont accept submitted units with /etc/sysconfig/ files which 
means those that still want to do this will need start carrying patches 
in the form of EnvironmentFile=-/etc/sysconfig/$SERVICE against upstream 
units to add this behaviour to units.

Doing so would go against our upstream mantra I believe....

c) This is no longer necessary since users really should be following [1]

iptables -L or for the exact initscript command that was used, run 
/usr/libexec/iptables.init status

iptables-save

or for the exact initscript command that was used, run 
/usr/libexec/iptables.init save

What's happening here is that sendmail is daemonizes itself in a racy way.

It exits the original process before the child writes the PID file which 
means that when systemd attempts to read the service's PID file, it is 
not there yet.

The proper steps to daemonize a process are described and can be found 
in [2]

No we are not however since [3] all path should really be pointing to 
/run at this point instead of that symlink...
