Hello!

I guix-pulled to something recent and got an error that was something
like "cannot stat: "my-root"".

My operating-system has sections like:

  (mapped-devices
   (list (mapped-device
          (source (uuid "97c130e9-edf4-40e4-8bfc-88fba056ffce"))
          (target "my-root")
          (type luks-device-mapping))))

  (file-systems (cons (file-system
                        (device "my-root")
                        (mount-point "/")
                        (type "ext4")
                        (dependencies mapped-devices))
                      %base-file-systems))

I guix-pulled to the titular commit and was able to reconfigure
successfully. Did something change in
424cea8083a4cee63290c80235aed61bd12affb1 or near there that could have
caused what I observed?
