Subject: resolve: always read /etc/resolv.conf on reload systemd-resolved
X-Git-Tag: v259-rc3~11
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ca1d2ae5d6bedfbd387427409fb331e223512ad9;p=thirdparty%2Fsystemd.git

resolve: always read /etc/resolv.conf on reload systemd-resolved

When systemd-resolved is used in resolv.conf foreign mode, reloading the
systemd-resolved daemon does not read resolv.conf when not touched since
the last time resolved read the file. Since the DNS servers list is
flushed during a reload, resolved forgets about the servers
in /etc/resolv.conf

When reloading the daemon it is expected that all configuration is
reloaded regardless of the disk timestamps.
