Forceful server reboot on VPS

[Karateka]

I'm not sure if this is a bug, so I am posting it here first.
We are using WHM in a Centos 5 OpenVZ container.
OpenVZ requires a file /reboot in order to reboot a container as there is a cron job on the host node that calls

/usr/share/vzctl/scripts/vpsreboot

(a script that checks all containers every 5 minutes for this file and reboots the container in question if it finds the file).

To get the file /reboot created on a Graceful Server Reboot, I opened

/etc/rc.d/rc6.d/S01reboot

and added

>/reboot

just after

# Kill all processes.

This does not fix Forceful Server Reboots though.

When I attempt a Forceful Server Reboot, the file is not created.
I noticed that just before the server shuts down, these processes are active:

root     28149  0.0  0.4  78100 26636 ?        S    03:42   0:00 /usr/local/cpanel/whostmgr/bin/whostmgr ./forcereboot
root     28151  1.0  0.0   3616   368 ?        D    03:42   0:00 /sbin/reboot -f

So my question is: How do I get the /reboot file created when a forceful server reboot is done through WHM?
