Yeah, definitely a good approach.

I've also considered using functions that could be overriden in the
init.d scripts.  The init-d-script could contain

  do_restart() {

and the init.d script could contain a different implementation:

  do_restart() {
     ... something else ...

The last definition would be used. :) But it would be hard to know if
do_reload() exist and will do something sensible, so variables are
perhaps a better approach.  Is there some way to figure out if a
function exist, without calling it?

Happy hacking
