TLJH Adding data for all users from SMB mounted directory, without copying or uploading

Goal
I have a version of TLJH running on a machine. The machine contains an smb shared drive mounted on it, with data that I would like to have available to all users on spinup. The drive is too large to copy to local.

What I’ve Tried
I’ve tried following the instructions here to share data with users via symlink, but this isn’t showing anything, possibly because (1) the mount is at /data, not /srv/..., or (2) because I haven’t uploaded the data via the instructions here.

Is there a way to make the data available to users, without copying it?

If the permissions are correct on the data mount all user should be able to access it. What error do your users see?
