In 1:4.2.8p3+dfsg-1, the default config was changed to
"Use pool instead of server". This needs a corresponding
update to /etc/dhcp/dhclient-exit-hooks.d/ntp, since the
DHCP specified servers now get added to the default pool
config instead of replacing them.
This affects Xenial only as the Yakkety build includes the upstream fix (1:4.2.8p7+dfsg-1).

[Test Case]
mterry isn't sure on this. Robie or Philip, do you have simple instructions?
[Regression Potential]
As noted in comments #1 and #2, this SRU might surface an issue if the user is receiving a broken set of NTP servers.
And as noted in comment #4, some people might be hackishly using the distinction between spaces and tabs in the config file to trick our current hook. Debian has gotten rid of that distinction, so that hack will stop working on distro-upgrade anyway. The fix is *probably* going to help more people who unintentionally mixed the two up rather than the few that are relying on that bug. But that bit can be easily dropped from the SRU if ya like. |

[Test Case]
philroche: This surfaced for me initially while testing on GCE. On GCE NTP servers are provided via DHCP so the easiest test case is to launch an instance on GCE without our workaround configured.
One such image is "daily-ubuntu-ntpdebug-1604-xenial-v20170331" in project "ubuntu-os-cloud-devel"
To start an instance of this image:
`gcloud compute instances create daily-ubuntu-ntpdebug-1604-xenial-v20170331 --image-project ubuntu-os-cloud-devel --image "daily-ubuntu-ntpdebug-1604-xenial-v20170331"`
Then run `ntpq -p` which should, once ntp is patched, return only one entry 'metadata.google' and should not return any of the ubuntu NTP pools.
