> systemd-nspawn is probably the only project without such a name

Add sd-tmpfiles to the list IMO. While it still create and manages temporary files its more managing almost any type of system file. From creating them to managing their permissions or making symlinks when needed.

I am a strong advocator of renaming it systemd-sysfiles to match the systemd-sysusers which is somewhat related (e.g. tmpfiles using users created from sysusers). But it probably won't happen for a while if at all due to backwards compat.
