firstboot (in the old days) imported system-config-date to configure the
date, time, and whether NTP was used. Its configuring of NTP required an
NTP client to be installed. By having chrony conditional in @standard, it
1) that when system-config-date (and by proxy, firstboot) were installed,
we'd have a NTP client so it could ocnfigure successfully
2) that we defaulted to chrony as the client as intended by the F16 feature
Nowadays... many things use timedatectl & the systemd service to set the
NTP status. It does not directly bring in any ntp client, intentionally.
(not needed for minimal installs)
While anaconda will bring chrony in for the live images, we probably
want to add a similar conditional for gnome-control-center, so GNOME
images/installs make sure to install a working NTP setup. Matthias?
