Should we add a touch /var/lock/subsys/capi

I am just thinking about how the /etc/rc.d/rc script determines whether
to run the K script is based on the existence of the
/var/lock/subsys/$subsys file....  Or perhaps the capiinit command does
this?  Without it, we may not properly shut down the service as the
system comes down?
