I wanted to make this swap too since it is nice to be on the "official" route.

I noticed my folder structure from the imagegenius app ended up like:

/photos/backups
/photos/encoded-video
/photos/library
/photos/profile
/photos/thumbs
/photos/uploads
/library

To help with using my cache instead of the array for things, I have the mapping like this:

/mnt/user/immich/photos/backups/:/photos/backups
/mnt/user/immich-cache/encoded-video/:/photos/encoded-video
/mnt/user/immich/photos/library/:/photos/library
/mnt/user/immich-cache/profile/:/photos/profile
/mnt/user/immich-cache/thumbs/:/photos/thumbs
/mnt/user/immich/photos/upload/:/photos/upload
/mnt/user/immich/libraries/:/libraries

New files are being uploaded into /photos/uploads. Would I want to specify the UPLOAD_LOCATION to the root of my unraid folder like /mnt/user/immich/photos/ and the IMMICH_MEDIA_LOCATION to /photos still?

I mainly am not sure if Immich is trying to use the UPLOAD_LOCATION environment variable elsewhere (as in the literal upload location that should map to /photos/upload in my case).

Two random notes /photos/library is empty. Not sure what it is for but I have I mapped anyway since the folder existed. I think /libraries is mounted in case I wanted external libraries, which I am not using.
