Which dependency exactly do you want to get rid of?

Please note that there is an official replacement for ntpdate called sntp, which is in the sntp subpackage of ntp and it includes a service similar to ntpdate. > == Scope == > Proposal owners: Need to re-engineer the startup task for ntpdate ( > /etc/init.d/ntpdate, NOT /usr/sbin/ntpdate ); or figure out if this is > something that is more easily created via a cron job.

It's very important that the time when the program is executed is not aligned to any second/minute/hour (as it would be with cron) to avoid flooding the public NTP servers. -- Miroslav Lichvar -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
