cs m1 native runner cannot bootstrap itself

[bishabosha]

./cs install --channel my-channel cs installs a failing runner

maybe I am being too quick to try this out before any announcement but here were the steps.

download native M1 runner from https://github.com/VirtusLab/coursier-m1

curl -fL https://github.com/VirtusLab/coursier-m1/releases/download/v2.1.0-M6-44-gc47ecec07/cs-aarch64-apple-darwin.gz | gzip -d > cs
chmod +x cs

then the downloaded cs works fine:

$ ./cs version
2.1.0-M6-44-gc47ecec07

but if I install the cs native runner from an app descriptor my-channel/cs.json (based from https://github.com/coursier/apps/pull/164)

then it fails:

$ ./cs install --channel my-channel cs
