Unable to install ZFS on the Debian image for Rock 5B

[jakubgs]

I'm trying to setup a NixOS installation on the NVMe with ZFS on my Rock 5B, but none of the images that work actually can have the ZFS module compiled. When I try it fails with:

rock@rock-5b:~$ sudo apt install zfs-dkms zfsutils-linux
...
Setting up zfs-dkms (2.0.3-9+deb11u1) ...
Loading new zfs-2.0.3 DKMS files...

dpkg: error processing package zfs-dkms (--configure):

I'm not sure if it's because of the old kernel or some Rockchip specific patches for the kernel.
