O.K. My understanding is (not saying it is right, just saying it is my current understanding):

. Without NTP type changes to a default install, the once run of ntpdate during boot will use ntp.ubuntu.com (91.189.94.4, which reverse lookup gives europium.canonical.com)

. If ntpd is installed, then it is unclear as to what NTP server will be used during boot. My system seems to have used 184.105.192.247 ( 247.conarusp.net ).

. If ntpd is removed via "sudo apt-get remove ntp" then the /etc/ntp.conf file stays. It remains unclear as to what NTP server will be used during boot. My system used 216.194.70.2 ( tb.mircx.com ).

. If all ntp files are purged via "sudo apt-get purge ntp" then the /etc/ntp.conf file is gone and during boot the original ntp.ubuntu.com address is used.

Yes, I see the entries in /etc/nto.conf as described in the subsequent sections of this chapter,
i.e. 0.ubuntu.pool.ntp.org. It is not clear to me why they don't seem to be used, but I do have ipv6 disabled on this computer and I do see ipv6 complaints in /var/log/syslog.

I agree that the line of this merge proposal should be left as it was.
