Just a note to say, I didn't apply this particular patch because you'd
already fixed it in Nixpkgs by the time I saw it, but I have now (finally)
integrated static cryptsetup in Spectrum, and it's working and it made
the initramfs much smaller and faster to build.  Thanks so much for the
work you put into it!
