** Description changed: The libnss-resolve postinst script inserts ‘resolve’ before ‘dns’ in the hosts line of /etc/nsswitch.conf. This makes DNSSEC validation impossible, even with DNSSEC=yes in /etc/systemd/resolved.conf, because if libnss_resolve returns a validation failure, glibc will simply fall back to libnss_dns. It also makes NXDOMAIN lookups twice as slow. - - The following syntax would preserve the fallback in the case that - systemd-resolved is not running at all, but allow systemd-resolved to - fail lookups that should fail when it is running: - - hosts: files resolve [!TRYAGAIN=return] dns
