What do I have to do to have zoneminder (I assume it is zoneminder not apache2) write group writable files?
umask 0002 in /etc/apache2/envvars doesn't seem to do it.
My initial chmod -R g+s * does, at least, seem to be being perpetuated for event directory creation, but the jpg's themselves are still going -rw-r----- (www-data:www-data).
