[Bug 1472056] Re: ntpd can use stale /var/lib/ntp/ntp.conf.dhcp config

[Simon Déziel]

The stale file was apparently left by /etc/dhcp/dhclient-exit-
hooks.d/ntp. Since this dhclient script updates the ntp.conf.dhcp file
when a new NTP server is advertised via DHCP, it should be OK to always
use the most recent file between /var/lib/ntp/ntp.conf.dhcp and
/etc/ntp.conf.

The attached patch changes the initscript to use
/var/lib/ntp/ntp.conf.dhcp only if it is newer than /etc/ntp.conf.

** Patch added: "Only use /var/lib/ntp/ntp.conf.dhcp if it is newer than /etc/ntp.conf"
