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.
