Ah, yeah it could be SELinux related. Can you test it on a machine with SELinux disabled (but all other bits - OS, distro, python version, etc) the same to see if SELinux is the problem? systemdspawner requires full access to systemctl, and since systemctl is very powerful I can imagine SELinux disabling access to it by default. If SELinux is the problem, need to find some way of letting jupyterhub have full access to systemctl via SELinux.
