This is possibly a good idea. However, if you're gonna be doing this, why
not just remove the symlink from /etc/rc2.d? When you want the daemon
back recreate the symlink. I'm under the impression that package updates
would recreate this link, so maybe that wouldn't work very well.

How is "chkconfig network off" any better/easier than "/etc/init.d/network
stop" (aside from the fact it won't get restarted when you reboot)? I
thought that's what different runlevels were for, having different daemons
started when you boot. Maybe I'm just thinking that mucking with
/etc/rcS.d/ as easy enough, but I suppose a chkconfig would be easier for
those less familiar with the init system.
I don't like the idea of adding this check to each init script. Wouldn't
it be better to add this check to /etc/init.d/rcS when it goes through the
/etc/rcS.d/S??* scripts (since the chkconfig parameter has the same name
as the init script minus the S??)?
