I'm top-posting on a bottom-post thread, and I'm replying to myself to retract what I said below. The executable I found, /lib/systemd/systemd-udevd, did not come with the libsystemd0 package. It was already there.
If someone knows how to tell if a library was used by a program, I would like to learn how that is done.
