ZFS on Guix |

Hi guix-developers,
I'm trying to get ZFS working on a test VM running Guix System.
Attempting to do a simple `guix install zfs` does not work, as I reported in
https://issues.guix.gnu.org/45401 , ZFS 0.8.5 is only up to kernel 5.9 but
latest guix has kernel 5.10.
I created a procedure to modify the base `zfs` package and compile it for a
different Linux kernel:
```scheme
(define (make-zfs-package kernel)
(package
(inherit zfs)
(name (string-append "zfs-for-"
(package-name kernel)
"-"
(package-version kernel)
"-version"))
(arguments
(cons* #:linux kernel (package-arguments zfs)))))
```
Then in my system configuration `.scm`, I selected a specific Linux and had its
module added to the boot and had it loaded in a Shepherd service:
```scheme
(define system-kernel linux-libre-5.4)
(define system-zfs (make-zfs-package system-kernel))
;; ...
(operating-system
(kernel system-kernel)
(kernel-loadable-modules (list (list system-zfs "module")))
;; ...
(packages
(cons* system-zfs
; ...
%base-packages))
;; ...
(services
(cons* (service kernel-module-loader-service-type
'("zfs"))
; ...
%base-services))
;; ...
)
```
As I documented here: https://issues.guix.gnu.org/45592#1
Now ZFS is loaded at boot (`lsmod | grep zfs` shows ZFS loaded), and `zfs
version` and `zpool list` don't error out.
However, when I created some extra space in the QEMU image and created a
partition `vda3`, I get an error in `zpool create tank vda3`.
The error is `cannot mount 'tank': Input/output error`.
I've also tried adding a new device to the QEMU boot as well, also the same
occurs.
Looking at a partition editor, the partition does get formatted as zfs, it just
won't mount.
Has anyone ever managed to get ZFS working on Guix? Any tips? Is it enough to
`modprobe` it in a system service or does it have to somehow be added to the
Linux command line? Maybe it only works on even older Linux-libre versions
than 5.4?
Thanks
