Hello,

This bug resulted in complete system breakage and I couldn't boot
anymore (systemd failing to load Kernel modules). I can guarantee that
this isn't only cosmetic.

I believe this isn't related to initramfs-tools, because downgrading
kmod and libkmod2 from version 26+20191223-1 to version 26-3 fixes the
issue. Initramfs now build (and run) correctly.

Regards,
