I think I've found that there are still some problems in parsing options.

1. The following command:

  GUIX_BUILD_OPTIONS=3D"--no-grub" guix package --help

gives the following error:

  guix package: error: no-grub: unrecognized option

So it makes impossible to use GUIX_BUILD_OPTIONS env var or did I miss
anything?

2. The manual says that =E2=80=98guix package=E2=80=99 =C2=ABsupports all t=
he common build
options that =E2=80=98guix build=E2=80=99 supports=C2=BB and the following =
command works
perfectly:

  guix build --system=3Di686-linux hello

However, the following command:

  guix package --system=3Di686-linux --install hello

gives an error again:

  guix package: error: system=3Di686-linux: unrecognized option

--=20
