OTOH if this area excites you, by all means, read up more, but probably about overlayfs instead, since that is what we are moving towards slowly (help needed!):

ways) to support overlayfs with overlayctl. Layers of RO and one or more
RW seem to work well (whether on RAM or overlay persistent partitions).
