Is it necessary to upgrade the userland to HEAD too for testing your fixes? There aren't great changes between RELENG_6 and HEAD afaik, and after doing some strong tests, I would like to returtn to RELENG_6, thus it would be more convenient to left userland alone, but if it is required, I'll upgrade completely to HEAD. What should I do? Cheers, Gábor Kövesdán
