Thanks doko, focal was Fix Released for the original initramfs-tools,
iirc. That made me miss the fix for Focal. I'm applying the same fix
(Eoan/Bionic SRUs) to Focal.

Alright, afaict what is happening is this:
In Focal I first faced this issue when upgrading kmod to
26+20191223-1ubuntu1.. but my reproducer was "update-initramfs" only.
The issue is that both: mkinitramfs (initramfs-tools) needs a patch to

For what it's worth, the versions of things in my test computers, all
servers, no GUI:

kmod; 26-3ubuntu1

At that time .. kmod was 26+20191223-1ubuntu1, now kmod is

made the mkinitramfs change buggy OR its something that was never
