Why

We built invalid ARM binaries (dynamically linked instead of statically) and did not notice it. Then I built an invalid i386 binary but directly noticed it because we run integration tests against it. Running these tests on ARM would give us better confidence on our binaries.

How

It is possible to run our ARM binaries with qemu in user mode.

This method is quite fast as the native kernel is used, only the binary is emulated.

It is very also easy for us to implement it as our binary is statically compiled and does not require any rootfs.

For example, from Nix, it is as simple as:

nix-shell -p qemu --run 'bash -c "qemu-arm result/bin/garage"'
