Many thanks for the many, many replies I received. As of this posting,
here's who answered:

The solution I used was to change the /etc/rc.local (for SunOS) or
/etc/init.d/autofs (for Solaris) call to the automounter daemon. The
now looks like this:

        automount -D APPSERVER=sunosserver && echo -n ' automount' (for SunOS)
        /usr/lib/autofs/automountd -D APPSERVER=solarisserver > /dev/console
2>&1 (for Solaris)

In the table, I now have

        /usr/application $APPSERVER:/export/application

After rebooting the systems, this now works. Many thanks to Anchi for
suggesting this way.

One suggestion I received said to use different auto.master maps on the
two different types of machines, with each auto.master pointing to a
different file. I didn't like this one because it required maintaining
several auto.master files on many machines.

Someone else suggested AMD. I was under the impression that AMD and
were the same things. Feel free to correct me if I'm wrong here.

Another idea was to use a complex series of links, different for each
architecture. I discard this because it struck me that there must be a
simpler way.

Several people suggested using the automounter ARCH variable. I could
done this had I moved both sets of applications to the same server. Then
my could have looked like:

        /usr/application server:/export/application/$ARCH

This suggestion would have worked as well.

Other people mentioned the OSREL variable. I've been told by one
that OSREL isn't supported by the SunOS automounter. I haven't tried it

Another really good idea, which I almost used, was submitted by Steve
Ehrhardt. He suggested have the ypmake's Makefile create a copy of
auto.master, called auto_master, with appropriate links to the
Since SunOS doesn't use auto_master but Solaris does, the maps will be
used correctly. I started to implement this when I realized that my
boxes don't use auto_master, they use auto.master. I don't have
anywhere on my Solaris boxes and there is no such map in my domain.

Once again, thanks for the really good and fast responses!
