Maybe an option would be if %current-system != host-system run guile using qemu-arm? > An option would to have ‘gexp->file’ produce a fixed-output derivation > (it can compute the hash of the output on the host side). > > Or maybe we need another mechanism similar to fixed-output derivations > to define equivalence classes of derivations. I'll have to read up on fixed-output derivations. Can you give me an example of where they are used currently?
