Control: reassign -1 ntpsec

Actually, I think it's better to just reassign the bug report and let Richard decide whether he closes it as wontfix or ships such an integration snippet.

Richard, if you are interested in shipping such a ntp-units.d snippet and you have further questions, please ask.

It looks like Systemd's timedatectl does not recognize ntpsec. Using
it results in 'NTP service: n/a':

$ timedatectl
               Local time: Wed 2024-03-06 12:35:32 EST
           Universal time: Wed 2024-03-06 17:35:32 UTC
                 RTC time: Wed 2024-03-06 17:35:32
                Time zone: America/New_York (EST, -0500)
System clock synchronized: yes
              NTP service: n/a
          RTC in local TZ: no

According to <https://wiki.debian.org/DateTime#Installing_NTP>, ntpsec
is an option for Debian 11 and below; and default for Debian 12 and
above.

I searched for an upstream bug at <https://github.com/systemd/systemd>
(is that the right place?), but there were no relevant hits. See
<https://github.com/systemd/systemd/issues?q=is%3Aissue+ntpsec>.

Also see <https://lists.debian.org/debian-user/2024/03/msg00145.html>.
That's the debian-users mailing list discussion with GW's comment.

If an NTP service want's to be recognized by timedated, it needs to ship a config snippet in /usr/lib/systemd/ntp-units.d/
See man systemd-timedated


LIST OF NETWORK TIME SYNCHRONIZATION SERVICES
       systemd-timesyncd will look for files with a ".list" extension in ntp-units.d/ directories. Each file is parsed as a list of unit names, one per
          ^
           this is a typo, should be systemd-timedated [1]
       line. Empty lines and lines with comments ("#") are ignored. Files are read from /usr/lib/systemd/ntp-units.d/ and the corresponding directories        under /etc/, /run/, /usr/local/lib/. Files in /etc/ override files with the same name in /run/, /usr/local/lib/, and /usr/lib/. Files in /run/        override files with the same name under /usr/. Packages should install their configuration files in /usr/lib/ (distribution packages) or
       /usr/local/lib/ (local installs).

       Example 1. ntp-units.d/ entry for systemd-timesyncd

           # /usr/lib/systemd/ntp-units.d/80-systemd-timesync.list
           systemd-timesyncd.service

       If the environment variable $SYSTEMD_TIMEDATED_NTP_SERVICES is set, systemd-timesyncd will parse the contents of that variable as a        colon-separated list of unit names. When set, this variable overrides the file-based list described above.


systemd-timesyncd and chrony do this properly.

# apt-file search /usr/lib/systemd/ntp-units.d/
chrony: /usr/lib/systemd/ntp-units.d/50-chrony.list
systemd-timesyncd: /usr/lib/systemd/ntp-units.d/80-systemd-timesync.list


I've CCed the ntpsec maintainers.
If they have interest in shipping such an integration, then we can reassign the bug report. Otherwise I'll just close it, as there is nothing we can do on the systemd side

Michael
