[PROBLEM] DLNA database needs to be rebuilt every boot.

[DRONE7]

It may have to do with the fact that it's started before NAS source is mounted during moOde startup. Maybe it needs to have the source mounted before it starts??

when miniDLNA is stopped in UI its cache is also cleared which includes its database.

Yes..that describes the problem perfectly... cache is not kept between boots and miniDLNA starts ahead of the NAS in boot order.

Is there any downside to keeping the cache ? or linking its update to the library update ?

Is there a code line that could be commented that would cancel the cache clearing..? just to try and see after a cold start if the clients would find the server.
