Ok, I took another look at what is going on. I think the problem is that the NFS share is being mounted one directory level lower than what I need.
I have this directory structure on the NFS export:
where Music-Raw is where I keep the files I’ve purchased / downloaded (might have multiple versions, it’s backed up externally, etc.) and Music is the “view” folder I want Volumio to import from. I have symlinks from Music pointing to Music-Raw.
The export is being mounted at …/media/Music but it actually needs to be mounted at just …/media for this to work as I want.
So I guess my actual question is: how do I get Volumio to mount X but only look for music in X/Y?
Is there any way to do that in the Volumio UX or do I need to manually mount and have Volumio import from the “local” FS?
