[regression potential] any regression would likely cause the DNS configuration that dhclient gets to not be properly reported to systemd-resolved, resulting in problematic/broken systemd DNS resolution. [scope] this is needed in b/f this hook was removed from systemd starting in g, and the hook was not yet added in x, so this change is needed only in b and f. [original description] When starting/using `dhclient`, it will often return an error such as: cmp: EOF on /tmp/tmp.yCyV6zBzhB which is empty This is due to the use of `cmp` in "/etc/dhcp/dhclient-enter- hooks.d/resolved" Because the $oldstate file can be empty, or different, it should use `cmp --quiet` This happens when "/run/systemd/resolved.conf.d/isc- dhcp-v*-$interface.conf" files do not exist, or when the content changes.
