Right, this is an issue with how we translate the menu-entries to sexps
through `menu-entry->sexp`, which then get embedded into a g-exp via
`operating-system-boot-parameters-file`!  We didn't take into account
non-string devices there.  The following two patches should fix the
issue and introduce some tests for it.

Best,
