Add a blank build.yaml file in the same directory


ok, fixed now, is new feature?

It’s a bug

@ludeeus , is this also related?

when i try in config.json this :

"host_network": false
i receive this error when i start it :

ioctl SIOCSIFNAME rename: No such file or directory

not sure, didnt try on supervisor 2021.2.3 , when i set it to true , it works
