+??? info "Follow Symlinks"
+    When mounting to a different location than `/nfs` or `/user` **locally**, one has to set the `follow_symlinks` option
+    so that symlinks e.g. pointing to a folder somewhere in `/nfs/` (which locally does not exist) are followed correctly, i.e. to the path on the remote machine.
+    This is not needed when mounting to `/nfs` or `/user` as the symlinks would point to these locations anyway,
+    but that comes with its own problems, as the mount needs to be done as **root** in these cases and might not be valid for other users.
