Custom kernel needed for task isolation and docker features
Currently a custom kernel must be built before using the docker cymac.
The stock buster kernel runs docker fine, but lacks options like CONFIG_NO_HZ_FULL
that are needed to provide robust task isolation.
The rtcds kernel has the task isolation features, but failed to start docker due to some other missing capability (I didn't make a note of what it was).
Perhaps docker support can be added to the rtcds kernel, so docker-cymac can work "out of the box" with Debian+cdssoft as the host OS.
