Why does initial-setup fail parsing the anaconda-ks.cfg post installation of Red Hat Enterprise Linux 7.2 Kickstart?

Issue

• Kickstart Installation done using kickstart file with firstboot --reconfig.
• After reboot, no initial setup windows is displayed whereas initial-setup-graphical service is aborted because error in /root/anaconda-ks.cfg
• The kickstart partitioning is as follows.

clearpart --all --initlabel
part /boot  --size=500 --fstype=xfs --asprimary
part pv.01  --size=1000 --grow
volgroup vgsys pv.01
logvol / --fstype=xfs --name=rootvol --vgname=vgsys --size=9000
logvol /tmp --fstype=xfs --name=tmpvol --vgname=vgsys --percent=2

• The error while starting the service is as follows.

[root@localhost ~]# service initial-setup-graphical start
Redirecting to /bin/systemctl start  initial-setup-graphical.service
[root@localhost ~]# service initial-setup-graphical status
Redirecting to /bin/systemctl status  initial-setup-graphical.service
