[csw-maintainers] cswinetd and cswetcservices?

It tries to.  The heuristic used to determine whether or not to add
the line is:

/usr/xpg4/bin/grep -q "^$svcname[[:space:]].*$port_proto.*$PKGINST" /etc/services

The lines added by the CAS include a '# CSWfoo' as a suffix to
indicate they were added by the script.  I guess the detection should
likely just look for: "^$svcname[[:space:]].*$port_proto"

This would better handle things not added/maintained by the script
itself and thus situations like yours.  Do you see anything wrong with
this for your (or other) uses?

(The r.cswetcservices script doesn't alter the /etc/services file at
all...)

I need to review some docs (and personal uses) of the cswinetd script
to answer the other question...

Thanks
-Ben
