hdpvr requires kernel modules, including the ir module from the
staging tree. That means a container doesn't really improve my
overall system uptime if I still have to reboot the host for a driver
glitch.

Look, I'm pretty familiar with virtualization and I'm not looking for
an argument about why I've chosen this or that. I have a slave that
is sufficient for the basic task of converting an hdpvr into a network
streaming device, but not cut out for compute tasks like
mythpreviewgen. I can restrict other jobs to not run on this slave,
can or can I not restrict mythpreviewgen? Thanks,
Alex
