The 'HEADS UP' post announced the regression was fixed with HEAD (8-CURRENT) r188570 and would be MFC'd to 7-STABLE [3]. Today, I upgraded one of these machines from 7.1-RELEASE-p4 to 7.2-RELEASE-p3, and camcontrol(8) still reports the output above. I found a USENET post [4] from early August reporting the same behavior on 8.0-BETA2. Is this behavior in fact a continued regression? Is manually setting the number of tags with -N the only workaround? Thanks in advance.
