Using Immich in combination with NAS permissions (sopuli.xyz)

Hi all, I'll cut to the point: is anyone out there running a NAS with multiple users, and each user has their own media folders and files that belong to them, with share access to those files (samba), and separately is also running an instance of Immich (as its own user) that in some way has access to these files and folders, AND is able to upload new files, while maintaining the NAS user ownership/permissions on those files?

In my current setup, each user's media files have permissions user:media 740 (so the "media" group has read access). The Immich user is in the media group. I then have the NAS files mapped as read-only, and added in Immich as external storage per user. This means I'm currently not uploading anything. (If I do, they get stored separately in Immich, not merged with the rest of the media files).

I could instead make the dir writable by the media group, map each NAS user's media directories directly as their Immich upload location (and fix up the Immich file naming/organization so that it matches), but I would still have the problem that it would create new files as the Immich user on the NAS, not the specific user.

Is there a clever permissions solution here I'm missing, or is it a lost cause to try and have both coherent per-user permissions on the NAS/samba share, AND use Immich? I don't really want a script that runs and chmods everything to user:media periodically. Feels hacky, and then Immich isn't able to change/delete any files, but that might be the only solution...

Generally, accessing files both as a share and through an app is not well supported. If Immich doesn't support setting ownership, you might be able to patch it to add the feature.

Otherwise, I'd probably stick to the user-group model you have currently, and do the chown/chmod. Immich should be able to fully manage files as long as it has the group permissions necessary (g+rw).
