You have been subscribed to a public bug: maas images utilize cloud-initramfs-dyn-netconf . The way this works is basically: * /etc/network/interfaces in image is a link to ../../run/network/dynamic-interfaces * kernel command line 'ip=' convince the initramfs to bring up networking using 'ipconfig' example: ip=::::maas-enlist:BOOTIF * ipconfig writes files in /run/net-*.conf for each interface it configures. * cloud-initramfs-dyn-netconf module writes /run/network/dyanmic-interfaces based on /run/net-*.conf files that 'ipconfig' creates.
end result is that after the move to real root, /etc/network/interfaces should be a symlink to /run/ that ends up having something like this: | ## This file is generated by cloud-initramfs-dyn-netconf | auto lo | iface lo inet loopback | manual eth0 | iface eth0 inet dhcp | dns-nameservers 192.168.64.3 | dns-search maas resolvconf seems not to be working as well as it should be. In vivid (now using systemd), I have only the resolvconf header in the file. in all other supported ubuntu releases, doing the above results in functional resolv.conf via resolv.conf.
