weeks ago). Didn't realize about it until I couldn't initiate X session

Deleting the file solves the "main issue" and I'm able to log in
What the heck? I woke up to a 9GB+ logfile (/var/log/uvcdynctrl-
udev.log) on the root partition and "no space left on device" errors.
I'm thinking we should pipe that logfile to post in this thread and see
how long it takes to get attention. :D

I think what is really needed is to have the logfile added to the

Is there a workaround meanwhile to deny a process writing to that file?
Maybe chmod
