Add support for IPv6 only installations
there are more and more IPv6 only environments that don’t facilitate DHCP (v6) anymore. Clients configure themselves after receiving “Router Advertisements”, including DNS information. (Alpine) Linux correctly handles the IP address assignment (i.e. doing nothing, the kernel takes care of it), however there is no support for DNS information on the current installation medium and thus packages cannot be downloaded.
The main problem that needs to be solved is to add DNS information from router advertisements into /etc/resolv.conf.
There are multiple ways to solve this:
- install rdnssd
- use a dhpcv6 client that allows failing dhcpv6 request, but still reads router advertisement information
As more and more networks become IPv6 only (and I in particular deal with many of these on a daily basis), I would appreciate having IPv6 DNS support in the installation medium.
Please let me know if you need further information or access to a test network.
