..no mention of it down my /etc/initramfs-tools/ tree, and, it
should have been in /usr/share/initramfs-tools/modules or in e.g.
/usr/share/initramfs-tools/modules.d/modules.vdev ?

..aaand, my initrd.img-4.9.0-2-rt-amd64 played tough, so more torture
ideas were needed, Osamu Aoki's getinitramfs script from Debian's
#790095 squeezed out my trashed cpio archive, which contains evdev
and vdev and a suspect "/conf/modules" with no mention of neither
vdev nor evdev. But it works and I wanna know how and why. ;oD

..could, indeed. ;oD
