It sources `/run/net-ens3.conf` (which is obviously not in correct shell syntax due to the space inserted between multiple DNS servers) to get network settings: ``` . "$f" || { echo "WARN: failed '. \"$f\"'" 1>&2; return 1; } ``` The bug is introduced by commit a77729e9, which replaced IP-config with dhclient. While IP-config seems to write each DNS in `IPV4DNS0`, `IPV4DNS1`, etc., dhclient write all DNS in `IPV4DNS0`, which is not expected by `netinfo_to_resolv_conf`. I can confirm 18.10 LiveCDs are affected.
