Public bug reported:

cloudinit/dists/rhel.py contains the follow code to determine if systemd
is in use:

    def uses_systemd(self):
        # Fedora 18 and RHEL 7 were the first adopters in their series
        (dist, vers) = util.system_info()['dist'][:2]
        major = (int)(vers.split('.')[0])
        return ((dist.startswith('Red Hat Enterprise Linux') and major >= 7)
                or (dist.startswith('Fedora') and major >= 18))


This will not produce the correct behavior on CentOS 7, Scientific LInux 7, or any other RHEL-based distribution.  Among other issues, this will prevent cloud-init from setting the system hostname correctly.  Because these distributions are treated like RHEL6 and earlier, cloud-init writes the persistent hostname into /etc/sysconfig/network, but the hostname is not read from this file when the system boots.

I propose that we replace uses_systemd with the following:

    def uses_systemd(self):
        return os.path.isfile('/usr/bin/systemctl')
