Hi, openstack-tox-py36 is now run on CentOS-8 after commit 31c4a7a18e2bd43d2893563b992c683c95baed6f was merged. I noticed Python.h is not installed so we cannot install python modules which require compilation. An example is found at [1]. Do individual projects explicitly install python-dev or will we handle it in the common zuul job? Before proposing a fix, I would like to hear our direction.
