(Get the code!)
aoetools is effectively unchanged, and their initramfs_hook is the same since xenial.
in the initramfs-tools the changes between 18.04 LTS and 20.04 LTS are that for automatic IP bring up, more methods are now supported with more robust IPv4 DHCP and IPv6 DHCP.
Was your 18.04 LTS installation customized to prevent DCHP in the initrd? Or was DHCP attempted in 18.04 LTS and simply was failing, keeping things working? Is this something you can rectify with preup ifupdown hooks, such that dhcp leases that are not needed are removed in the running system? Or is booting with ip=none parameter sufficient for you?
Please indicate what has changed, to cause failures. Because the behaviour of aoetools in stock configuration between 18.04 LTS and 20.04 LTS is expected to be the same, with dhcp being performed from the initrd by default.
