[Message part 2 (message/rfc822, inline)]

From: Simon South <simon <at> simonsouth.net>
To: guix-patches <at> gnu.org
Subject: [PATCH 0/1] services: openntpd: Remove support for deprecated "-s"
 option.
Date: Mon, 11 Jan 2021 12:02:34 -0500

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.
