update-initramfs / mkinitramfs fails to add ANY kernel modules

[Michael Neuffer]

The error occured which the update last Saturday or Sunday.

(Re-)Building an initrd results in unusable initrds

Checking the directory shows that there is not a single module included in the archive.
The initrd itself is much smaller as a first visual indication.

Booting a kernel with such an initrd strands the machine in the initrd busybox
with almost no available devices (due to the missing kernel modules)

No kernel modules:
