[s390x] Use `aptman/qus` instead of `multiarch/qemu-user-static` #85

Closed chantra closed 1 year ago

chantra commented 1 year ago

multiarch/qemu-user-static does not support hosts other than x86_64. aptman/qus does. The command syntax is slightly different though.

This change update the systemd resource to:

To test, I confirmed that after using this new container, we could still run x86_64 containers in s390x hosts:

Before:

linux1@bpf-ci-runner-s390x-2:~$ sudo docker exec -ti 112b682130e9 bash
root@112b682130e9:/actions-runner# /usr/x86_64-linux-gnu/bin/ls
_diag  bin  config.sh  env.sh  externals  run-helper.cmd.template
run-helper.sh.template  run.sh  safe_sleep.sh  svc.sh

Updated systemd resource and restarted it:
