- Remove /mnt/storage/media from systemd.tmpfiles.rules (it's a ZFS dataset mount point)
- Add ExecStartPost to set proper permissions on ZFS-mounted media directory
- Update NFS research documentation with ZFS integration best practices
- Add section explaining ZFS mount point vs tmpfiles.rules conflicts
This resolves the potential conflict where tmpfiles tries to create a directory
that ZFS wants to use as a mount point for the storage/media dataset.
