[csw-maintainers] CSW packaged MTAs and /usr (continued from "CSWcswclassutils: it wants to write in /usr")

This should be:

... && ln -s <cswbin> <sysbin>

since the binaries won't be delivered to /usr.  I personally still
think this stinks (I use exim, but it's the same pita)...anyway, like
many other things on solaris, I'll continue to hit them with my
cfengine hammer.

Yes, the package tools would overwrite the link and restore the system
sendmail.  There is a setting that can be toggled to prevent
this...I'd have to look it up as I'm not sure what it is off the top
of my head.

Since we need to live with these unfortunate rules, I think your
approach of simplifying the package and providing 'guidelines' via
README.CSW is the best option.

HTH.
