AIUI, this is a followup to <http://bugs.gnu.org/20067>, and it’s
admittedly a shame that this isn’t fixed!

I still think that the approach proposed at
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20067#10> is more
appropriate; ‘menu-entry’ would always work, no duplication would be
necessary.

As a stop-gap measure, I would prefer to (1) allow:

  (menu-entry
    ;; …
    (linux #~(string-append #$kernel "/bzImage")))

(2) remove the “/bzImage” assumption and use the above idiom everywhere
in the current code, and (3) and have a hack along these lines to
correctly interpret (string-append …) in the ‘parameters’ file:
