Hmm, this won't work it seems anyway, as right after
log_parse_enviornment() and log_open() there is a call to:


log_set_max_level(udev_get_log_priority(udev));

So it seems that an evnironment parsing is very swiftly overridden -
which makes env parsing kinda pointless IMO.

Any thoughts?

CC'ing Tom as he changed the default log level to INFO recently in
2004d23a0fcaa6e74631057a2ff75594a038d86e which is likely why I'm seeing
the bubble up now...
