[IDEA] Ramplay.

I wonder if you could just use /run which is a tmpfs (ram file system). I think by default its configured with a size limit of 50% of total RAM. This can be changed by adding a manual entry in /etc/fstab

So in theory on a Pi-4/4GB model you could safely let /run have a 3GB size limit.
