Since that commit, merely evaluating 'vm-image.tmpl' would trigger the build of 'current-guix' so skip it. * tests/guix-system.sh: Do not try to build 'vm-image.tmpl'. 2022-02-18profiles: 'profile-derivation' rejects unsupported packages.Ludovic Courtès Previously user-facing commands would happily start building packages even if they do not support that system. With this change, all the user-facing commands reject unsupported packages without going further. * guix/profiles.scm (profile-derivation): Add #:allow-unsupported-packages?. Define 'check-supported-packages' and honor #:allow-unsupported-packages?. * tests/guix-pack.sh, tests/guix-package.sh, tests/guix-shell.sh: Ensure that unsupported packages are rejected. * tests/guix-system.sh: Pass "--system=armhf-linux" when attempting to build gnu/system/examples/asus-c201.tmpl.
