Alright,

I did this:

root@devuan:~# mkdir -p /tmp/initrd
root@devuan:~# cd /tmp/initrd
root@devuan:/tmp/initrd# zcat /boot/initrd.img-4.7.0-0.bpo.1-686 | cpio
-idmv 2>/dev/null
root@devuan:/tmp/initrd# ls
bin conf etc init lib run sbin scripts
root@devuan:/tmp/initrd# find . | cpio -o -c | xz -9 >
/boot/initrd.img-4.7.0-0.bpo.1-686.xz
281152 blocks
root@devuan:/tmp/initrd# ls -l /boot/initrd.img-*
-rw-r--r-- 1 root root 14795981 dic 15 08:17 /boot/initrd.img-3.16.0-4-586
-rw-r--r-- 1 root root 15916152 dic 15 07:57
/boot/initrd.img-4.6.0-0.bpo.1-686
-rw-r--r-- 1 root root 16239683 dic 16 09:32
/boot/initrd.img-4.7.0-0.bpo.1-686
-rw-r--r-- 1 root root 11799196 dic 16 11:08
/boot/initrd.img-4.7.0-0.bpo.1-686.xz
root@devuan:/tmp/initrd# file /boot/initrd.img-4.7.0-0.bpo.1-686.xz
/boot/initrd.img-4.7.0-0.bpo.1-686.xz: XZ compressed data

Sadly, booting with the 4.7 kernel and this new .xz initrd didn't work
either.
