  # s6-rc-compile generates built-in service definitions containing

  # cross-compile that derivation, those paths will be wrong --
  # they'll be for execline, s6, and s6-rc on the platform we're

  # We can detect this special case of s6-rc being used at build time
  # in a derivation that's being cross-compiled, because that's the

  # modify s6-rc-compile to use the configuration headers for the
