All, Is there a magic escape to allow passing --substitute-urls via GUIX_BUILD_OPTIONS?
$ GUIX_BUILD_OPTIONS="--substitute-urls=http://server1 https://mirror.hydra.gnu.org"; guix package -I guix package: error: https://mirror.hydra.gnu.org: extraneous argument $ GUIX_BUILD_OPTIONS="--substitute-urls='http://server1 https://mirror.hydra.gnu.org'" guix package -I guix package: error: https://mirror.hydra.gnu.org': extraneous argument $ GUIX_BUILD_OPTIONS='--substitute-urls="http://server1 https://mirror.hydra.gnu.org";' guix package -I guix package: error: https://mirror.hydra.gnu.org": extraneous argument $ ... other attempts involving apostrophes, quotes, and backslashes ... I can't seem to find the incantation that works. Cheers, Marco
