Correct replacement for 'birdc reload in all' in BIRD 3.1?

Hello, I'm currently running the following commands in a systemd.service as part of a systemd.timer: - rpki-client -B -c -j -m -o - bird -p -c /var/lib/rpki-client/bird - birdc configure soft - birdc reload in all Since upgrading from BIRD 2.16 to 3.1, the last command fails. However, https://gitlab.nic.cz/labs/bird/-/blob/stable-v3.1/doc/migration-bird3.md mentions just:

"Reload of filters is now done by reload filters command, contrary to just reload in BIRD 2.

Am I overlooking something? What's the correct replacement command for BIRD 3.1? Regards, Robert
