I'm trying to setup a system that can run in RAM with docker containers
(avoid SD card wear on Pi).
Due to RAM size limitation to load all system in RAM at boot, diskless
install is not an option in this case.
One alternative idea is to setup a traditional "disk" install and once
all set, run with overlaytmpfs=yes cmdline option.
However docker will fail to start under such configuration (possibly
overlay2 storage driver issue).

Is there a simple workaround to get docker working in such target setup?
Are there some |overlaytmpfsflagsoptions to be considered?
I could not find much documentations on this mode and options.

Thanks for any tip.
