System extensions!

@craftyguy Is this "extensions" like the layering method that the immutable fedora offers (Silverblue/Kinoite)?

When one or more system extension images are activated, their /usr/ and /opt/ hierarchies are combined via "overlayfs" with the same hierarchies of the host OS, and the host /usr/ and /opt/ overmounted with it ("merging").
