Yes! This.

I have one machine for network sharing storage and thus a user for login and r/w powers. The same storage is used by other machines to save the files, and so each autonomous user for CCTV and qBitTorrent needed to have the same UID as the Samba login, as well as qBittorrent share the UID with Emby, so each program had rw permissions and those containers had to be privileged (otherwise the permissions under ls -l would be ‘nobody nogroup’).
