[bug#45692] [PATCH 0/4] Even Better ZFS Support on Guix |

Hi all,
Sorry for the excessive number of patches.
This patchset contains 4 patches, two that add new features to Guix and do not
involve ZFS at all, one bugfix of the ZFS package, and one which makes
installing ZFS on Guix easy.
* Patch 1: Create an extensible service type that installs kernel-loadable
modules into the kernel.
* This allows a ZFS service to add the ZFS module to the kernel.
* Patch 2: Make the `file-systems` shepherd service an extensible target, so
that other services can add more requirements for `file-systems`.
* This allows a ZFS service to make `file-systems` wait for the ZFS automount
at startup, which is necessary in any case in order to ensure that ZFS has
scanned for ZFS pools installed in the hardware.
* Patch 3: Fix the ZFS package definition.
* Patch 4: Add a ZFS service type that installs everything needed for basic ZFS
usage!
I've tested the ZFS functionality in about a half-dozen VMs already, including
checking that the ZFS setup persists across reboots of the VM:
* No ZFS installed.
* With ZFS installed but without any ZFS pools.
* With ZFS pool that is automounted.
* With ZFS pool in legacy mode (needs manual `mount -t zfs poolname
/mountpoint`).
* Encrypted ZFS dataset (prompts passphrase at boot to mount).
* Encrypted ZFS dataseet as `/home` (prompts passphrase at boot to mount, user
`/home` directories are created and maintained).
Other bits of ZFS functionality would be *nice* but aren't in this patchset yet
(and at least for my purposes are not really necessary, except perhaps the
auto-scrubbing, I just need to wrap my head around `mcron`...):
* Auto-scrubbing of ZFS pools to ensure no data corruption.
* Auto-snapshotting of ZFS datasets to protect against user error.
* `/` on ZFS.
* `/boot` on ZFS.
* Managing ZFS "legacy" mountpoints on `(file-system ...)` declarations.
* Managing ZFS pool setup in the `operating-system` declaration somehow (not
sure how to do this).
Thanks
