I came up with a slightly different answer, which also works. I'm just documenting it here for reference. I copied debug-shell.service from systemd to /etc/systemd/system/root-shell.service. I modified the file as below because I wanted to start a root shell on /dev/console, and I also wanted the target to be multi-user.target. I then enabled the service as usual: # systemctl enable root-shell On boot, it starts a root shell with no login required.
