Before you get too far into configuring things, you may want to
seriously consider using version 3 instead.

You need to set a new class when you make the edit, then write a promise
that will run your command when the class is set.
My CF2 is out of practice, but something like this should work:
editfiles:
some_class::
{ /etc/sysctl.conf
AppendIfNoSuchLine "blah, blah, blah"
DefineInGroup "reload_sysctl_conf"
}
shellcommands:
reload_sysctl_conf::
"/sbin/sysctl -p"
