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

@joe9nf @craftyguy No, this is systemd-sysext, which just layers files on top of /usr/ so these new files (usually binaries) can be added without actually modifying /usr/ in actuality

@joe9nf @craftyguy """ 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").
