yup. i just think we would be better off automating the duplication, via CAS

The CAS.

pseudo-code:

[start of read filename from stdin loop]
case $filename in
    /etc/opt/csw/init.d/*)
        NEWfilename=/opt/csw/init.d/cswinitsmf/$PKGINST/`basename $filename`
        cp $filename $NEWfilename
        installf $NEWfilename
        removef $filename   # not sure this will be allowed though ;-)
        filename=$NEWfilename
   ;;
esac

   ## now proceed to do "normal" init processing on $filename, either way.

## Of course, the above would have to be tweaked for chroot, blah blah blah.
## If the removef is disallowed, above.. .then we simply "ignore"
files under /etc/opt/csw
## when it comes to remove time. we presume that they get handled by
their automatically
## duplicated copy in /opt/csw/init.d ?  IF /opt/csw/init.d/cswinitsmf
exists, that is.
## That handles the case of legacy installs done before newer version
of cswinitsmf installed.

I believe the above proposal meets that criteria. The only
"significant modification" is a one-time alteration of the cswinitsmf
CAS package.
