Description of problem:
The kickstart file used for installation has a group directive. But, after installation, it's not in /root/anaconda-ks.cfg.


    def writeKS(self, filename):
...
        if self.anaconda.isKickstart:
            f.write(self.ksdata.user.__str__())
            f.write(self.ksdata.services.__str__())
            f.write(self.ksdata.reboot.__str__())

f.write(self.ksdata.group.__str__()) is missing here definitely.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 6

How reproducible:
Always

Steps to Reproduce:
1. Install RHEL6.7 with a kickstart file including group directive
2. After installation, check /root/anaconda-ks.cfg

Actual results:
group directive is not in /root/anaconda-ks.cfg

Expected results:
group directive is written in /root/anaconda-ks.cfg
