Ideally, we=E2=80=99d use an actual UUID object (or a string?) here rather =
than
this Linux/udev-specific idiom.  So it would look like:

  (bootloader-configuration
    ;; =E2=80=A6
    (target (uuid =E2=80=A6)))

Would that work?

I believe using Guile-Parted we could map it back to a /dev name.

WDYT?
