Manual install of agent controller on Solaris 11.2 global zone won't start install, fails

Is the 12.2.2 AC install script buggy?  Note installing from the BUI *is not an option*, as our security prevents all direct root logins.  Hence we must manually install ACs.

root@lush:/var/tmp/OC/OpsCenterAgent# ./install -a

./install: -a: unknown option

Usage:  install -p <Proxy Controller>

./install[308]: : cannot open

Huh?  looked into script:

usage() {

    if [ "$myname" != "uninstall" ]; then

==>        echo_gettext "Usage:  $myname -p <Proxy Controller>" >&2 <==Note

        # we don't advertise the -c option since it should only be used in the context

        # of an EC/PC installer or uninstaller and when used we don't need to setup the

        # AC IPS publishers since the EC/PC already handle that.
