I have a system with an encrypted root. I have installed dropbear-initramfs and am able to SSH in and unlock root and boot fine. However once I boot I end up with both eth0 and br0 with the same static IP and thus networking is not functioning.
ifconfig eth0 0.0.0.0 gets everything going after boot, but I want to avoid having to load that in at boot as it feels very hacky. Looking for how to get initramfs to reset/cleardown/etc the eth0 interface to allow netplan to apply once the main system kernel boots.
The IP for initramfs is configured in /etc/initramfs-tools/initramfs.conf as follows
ethernets: eth0: dhcp4: no bridges: br0: interfaces: [eth0] dhcp4: no addresses: - 192.168.1.220/24 gateway4: 192.168.1.1 nameservers: addresses: - 220.127.116.11 - 18.104.22.168 search: - teese.net.au version: 2
I have tried setting IFDOWN=* in /etc/dropbear-initramfs/config to no avail.
Any tips would be appreciated. Cheers
