Advanced Configuration - kn6plv/Raven GitHub Wiki
Raven offers a number of advanced configuration options not available via the UI. For most people there's no need to modify these; but in some cases making changes is necessary.
raven.conf.override
Raven is configured using the configuration files raven.conf and raven.conf.override. Both files are located on the node in the /usr/local/raven directory. The user should only change the raven.conf.override file as the other will be overwritten whenever Raven is updated.
If raven.conf.override does not exist when you need to modify if, you should create it first. By default the contents should be:
{
}
as this is a JSON file.
