You mean with "echo foo >> /target//etc/initramfs-tools/modules &&
update-initramfs -u -k all"?
That was what I was doing, it's ok for the likes of us but not really
for more regular users who might be e.g. following docs to run Debian on

what led me to request a more convenient way to preseed this.
