You would add (flags '(bind-mount)) to the Scheme definition of
file-system.

Do I define the "spinning-disk-drive-goes-here" file system inside the dependency block and not in the main list of file systems, or do I define it in the usual place and then add some unique ID to the dependency block, or something else?

There's an example in this discussion:

Make sure to read the reply from Ludovic which completes the picture.

Does that help?
