[bug#45794] [PATCH 0/1] services: openntpd: Remove support for deprecated "-s" option. |

This patch removes support for OpenNTPD's deprecated "-s" command-line option
and the corresponding "allow-large-adjustment?" field from Guix's
openntpd-configuration record type.
Previously this option allowed OpenNTPD to make a single, arbitrarily large
adjustment to the clock at startup. In the current release this option has
been disabled[0] in favour of the use of authenticated constraints, and
configuring a service with "(allow-large-adjustment? #t)" now causes this
message to appear in /var/log/ntpd:
-s option no longer works and will be removed soon.
Please reconfigure to use constraints or trusted servers.
For systems like the ROCK64 that lack a battery-backed clock, generally the
solution is to replace the "allow-large-adjustment?" option with a setting
like
(constraint-from '("www.gnu.org"))
which will give OpenNTPD an independent estimate of the current time and allow
it to evaluate the trustworthiness of the configured NTP servers.
