maybe you misconfigured "mount-point" and "type"?

what about:

--8<---------------cut here---------------start------------->8---

 (define %store-fs ;; <--- This is what I want to add.
   (file-system (device (file-system-label "storage-fs"))
 	       (mount-point "/gnu/store")
 	       (type "btrfs")

--8<---------------cut here---------------end--------------->8---

WDYT?

AFAIK we can move /gnu/store anywhere **if** the system is not live,
like you did booting in "rescue mode"
