thanks
The solution is quite simple: Just return from dep_add_modules_mount()
when tmpfs is detected as fstype. A tested patch is attached.

Subject: [PATCH] Fix failure when / uses tmpfs
When initramfs-tools is run on a system with a tmpfs based root mount
point, it will fail:
root@host:~$ /etc/kernel/postinst.d/kdump-tools $(uname -r)
kdump-tools: Generating /var/lib/kdump/initrd.img-4.4.36-2
mkinitramfs: failed to determine device for /
mkinitramfs: workaround is MODULES=most, check:
grep -r MODULES /etc/initramfs-tools/
Error please report bug on initramfs-tools
Include the output of 'mount' and 'cat /proc/mounts'
update-initramfs: failed for with 1.
Bug-Debian: #856589
