Description of problem:
I tried running ipa-client-install today and it failed with:

Traceback (most recent call last):
  File "/sbin/ipa-client-install", line 2590, in <module>
    sys.exit(main())
  File "/sbin/ipa-client-install", line 2571, in main

When looking at systemctl status ntpd, I see:

ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled)

The systemd service file has:

[Unit]
Description=Network Time Service
After=syslog.target ntpdate.service sntp.service

[Service]
Type=forking
EnvironmentFile=-/etc/sysconfig/ntpd
ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS
PrivateTmp=true

[Install]
WantedBy=multi-user.target



and the /etc/sysconfig/ntpd has:

# Drop root to id 'ntp:ntp' by default.
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

# Set to 'yes' to sync hw clock after successful ntpdate
SYNC_HWCLOCK=yes

# Additional options for ntpdate
NTPDATE_OPTIONS=""



Though looking at rpmverify, it appears that:
S.5....T.  c /etc/sysconfig/ntpd


Looking at the ipa-client-install source code, it looks like we're forcing the
inclusion of the extra -u line into /etc/sysconfig/ntpd, which is rejected by
the ntpd binary.



Version-Release number of selected component (if applicable):
freeipa-client-3.3.3-2.fc20.x86_64
ntp-4.2.6p5-18.fc20.x86_64
