Optional features allow distros to define sets of transfers that can be enabled or disabled by the system administrator. This is useful for situations where a distro may want to ship some resources version-locked to the core OS, but many people have no need for the resource, such as: development tools/compilers, drivers for specialized hardware, language packs, etc We also rename sysupdate.d/*.conf -> sysupdate.d/*.transfer, because now there are more than one type of definition in sysupdate.d/. For backwards compat, we still load *.conf files as long as no *.transfer files are found and the *.conf files don't try to declare themselves as part of any features Fixes https://github.com/systemd/systemd/issues/33343 Fixes https://github.com/systemd/systemd/issues/33344
