Ah sorry, I was only thinking of the upgrade process itself. In your
particular scenario (having an EVPN zone configured as well) I'm afraid
there's currently no easy way of preventing the daemons file from
getting overwritten by the SDN module.

The defaults are set in the frr config generation module [1] and
currently not overridable. I guess we'd have to expose a way of setting
the default value for those daemons to 1 instead of 0.

Another way would be trying to detect if the status of the daemons needs
to change compared to the previous SDN configuration and only re-write
the daemons file in the case it really *needs* to change instead of
every time. But that is probably a bit more tricky.

Could you open a feature request on our Bugzilla?
