Hi,
I'm in the process of upgrading VyOS on our firewalls and currently testing the new image. I have an issue with keepalived-fifo.py that can't load the config when VRRP is initially configured. If I reboot vyos or restart keepalived it works correctly. This breaks executing transition-scripts.
Looks like the new image runs newer keepalived and keepalived-fifo.py file has been updated since VyOS 1.4-rolling-202108111528 we currently use.
