Think we should use vagga to build itself as for instance for #555 we'll need to compile openssl statically.

Have you any thoughts why does "image: pull & push" test fail? On my computer it passes.

I'm not sure what is the difference.

No idea. We have to make more debugging in the test.

I'm not sure what is the difference.

To not duplicate setup code from a build container into github-ci. For instance to install openssl we'll need to add something like:

    # https://qiita.com/liubin/items/6c94f0b61f746c08b74c
    - !Sh |
        ln -s /usr/include/x86_64-linux-gnu/asm /usr/include/x86_64-linux-musl/asm
        ln -s /usr/include/asm-generic /usr/include/x86_64-linux-musl/asm-generic
        ln -s /usr/include/linux /usr/include/x86_64-linux-musl/linux
    - !TarInstall
      url: https://github.com/openssl/openssl/archive/OpenSSL_1_1_1l.tar.gz
      script: |
        CC="musl-gcc -fPIE -pie" \
          ./Configure no-shared no-async \
          --prefix=/usr/lib/x86_64-linux-musl \
          --openssldir=/usr/lib/x86_64-linux-musl/ssl \
          linux-x86_64
        make depend
        make -j$(nproc)
        make install_sw

But possibly it's not a problem at all.

Yes, I think that's not a problem. Although, if rust-cache works for vagga-based builds, we can probably go either way.
