It's been a long while since I used clvmd, so they may have fixed this
since then, but there used to be a bug that clvmd would always start up
with debug logging, even if -d0 was set.

Luckily, dynamic disabling of debug mode worked and could be done
anytime after clvmd is started, using "clvmd -C -d0".

What I wound up doing was configuring swatch to monitor the logs, and
run that command if it saw debug messages!
