I was building upstream ntp as-is having --with-sntp=no as debian/rules does. And just as I assumed, the old 4.2.6 build "ignored" the "--with-sntp=no" and built it anyway. While the new one follows the order.
This was changed way back in: commit dd3be096e78eb8d13da36caad215c9f5c009b11a Author: <daveh...@shiny.ad.hartbrothers.com> Date: Sun Feb 20 20:23:00 2011 +0000 Attempt typical subpackage approach for libevent sntp test cleanup But this is just where 4.2.7/4.2.8 development started which is why it is different in 4.2.6 as in Trusty/Jessie. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1604010 Title: sntp missing Status in NTP: Unknown Status in ntp package in Ubuntu: Triaged Bug description: In Ubuntu 16.04, the binary file /usr/bin/sntp is missing from the package ntp. The associated man page /usr/share/man/man1/sntp.1.gz is still included. How to reproduce: $ sudo apt-get install ntp $ dpkg-query -L ntp | grep sntp /usr/share/man/man1/sntp.1.gz Expected result: /usr/bin/sntp was included in Ubuntu 14.04: $ dpkg-query -L ntp | grep sntp /usr/bin/sntp /usr/share/man/man1/sntp.1.gz The sntp program remains a very useful tool for interactively testing on the command line the offset of the local clock to a remote NTP server (like "ntpdate -qu [ntp-server]" previously). It should be included in the same package as its man page.
