Comment 18 for bug 1804822

For systemd and kernel, let's track that in separate bugs perhaps.

python-libguestfs from centos pulls in the kernel

I can confirm it is being pulled into
kolla/centos-binary-nova-compute-ironic currently but likely others as
well

looking at a recent CI run from kolla I'm seeing the kernel package
installed in the following containers

nova-libvirt
nova-compute-ironic
nova-compute
sahara-base

RPM dep tree
------------------
openstack-nova-compute -> python-libguestfs -> libguestfs -> kernel
nova-libvirt (container) explicitly pulls in libguestfs -> kernel
python2-sahara -> python-libguestfs ->libguestfs -> kernel
