Date: 2024nov27 OS: Linux Q. Fix for: systemd[1]: Failed to start systemd-binfmt.service - Set Up Additional Binary Formats A. It appeared with these other messages:

systemd[1]: systemd-binfmt.service: Start request repeated too quickly. systemd[1]: systemd-binfmt.service: Failed with result 'start-limit-hit'. systemd[1]: Failed to start systemd-binfmt.service - Set Up Additional Binary Formats.

Its just saying it was restarted too quickly (probably from the .automount). You can just tell systemd not to worry about it with:

systemctl reset-failed systemd-binfmt.service
