Package: live-boot Version: 1:20210208 Severity: important Tags: patch Hi,
We are using live-boot together with resolvconf. Our /etc/network/interfaces is generated on boot and uses a static config without DHCP. So the DCHP client in the initrd will be the only DHCP client. Once the system is booted, /etc/resolv.conf stays empty. When using resolvconf, writing the resolv.conf settings into `/etc/resolvconf/resolv.conf.d/base` is not enough. `/etc/resolv.conf` pointing to `/run/resolvconf/resolv.conf` will stay empty. So in addition to copying resolv.conf into `/etc/resolvconf/resolv.conf.d/base`, generate `/run/resolvconf/resolv.conf` by adding the head and tail. A tested patch is attached that generates /run/resolvconf/resolv.conf when using resolvconf. -- Benjamin Drung Senior DevOps Engineer and Debian & Ubuntu Developer Compute Platform Operations 1&1 IONOS SE | Greifswalder Str. 207 | 10405 Berlin | Deutschland E-Mail: benjamin.dr...@ionos.com | Web: www.ionos.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Hüseyin Dogan, Dr. Martin Endreß, Claudia Frese, Henning Kettler, Arthur Mai, Matthias Steinberg, Achim Weiß Aufsichtsratsvorsitzender: Markus Kadelke Member of United Internet
