Missed this message earlier... this seems like this should be the
default on pretty much all Fedora setups, with documentation on how to
change it if you secure the boot loader.
I wasn't aware this option existed, because it isn't documented in any
of the systemd man pages (and in fact there is no man page at all for
systemd-sulogin-shell or the emergency or rescue services). Now I see
there's an additional list of environment variables in
/usr/share/doc/systemd/ENVIRONMENT.md (which I didn't know I needed to
look for an environment variable to set, so I wouldn't have looked there
even if I knew the file existed).
