After reading this carefully, on one hand I understand the idea behind
handing the special case with no files supplied; but I realized that I
don't know enough about the intended way for the NFS sharing to work.
I've read our user guide page[1], and the wiki page[2].  IIUC, the NFS
sharing is done in such a way that there is a master machine onto
which CSW packages are installed and which serves the /opt/csw
directory in a read-only fashion.  Other machines mount this directory
via NFS and don't install the CSW packages at all.  It's enough to add
/opt/csw/bin to $PATH in order to access the utilities.

If you tried to install a package to a machine with read-only mounted
/opt/csw, I'm guessing that pkgadd would fail (is that true?), because
writing to the file wouldn't be possible.  If you don't run pkgadd on
client machines, how are daemons started?  The "empty input
cswinitsmf" idea above wouldn't solve that.

Sorry about backtracking, but I have to understand the background
before I can make any useful comments on a particular idea.
