>Environment:

SunOS sunchen 5.9 Generic_112233-12 sun4u sparc SUNW,Ultra-1

>Description:

        It appears to be a general trend in pkgsrc to replace a
        back-tick evaluation of commands `echo foo` with $(echo
        foo). Unfortunately, the SunOS /usr/bin/sh doesn't know the
        latter expression. And since rc.subr is only sourced by the
        rc.d scripts, there is nothing the script itself can do about
        the issue - other than change the $(...)s back to `...`s.

>How-To-Repeat:

        Build wip/isc_dhcpd on Solaris 9. Find that its rc.d script
        wants rc.subr, install the package, see a

[hf@sunchen] /etc # rc.d/isc_dhcpd start
rc.d/isc_dhcpd: syntax error at line 66: `_osname=$' unexpected

>Fix:
        (1) Change the $(...)s back to `...`s.
Or
        (2) Make sure that _all_ rc.d scripts installed use
            /usr/xpg4/bin/sh on Solaris.
