That answers my question then. The idea makes some sense, it’s sort of possible with the API, and yeah it might make an useful feature.
My initial reaction was: “Ought that not be –sync-once-with |all.” But that lead to …
Yeah, it’s a bit tangled if you have N partner devices and the folders are scattered over those partners. Might argue that the configuration is what it is. So one time means sync all the folders with all the partner devices or timeout. I.e. –sync-once-with-timeout <seconds>
Might be a role for args that narrow the configuration to a particular device of folder even for 24/7 syncing.
