It includes changes to how Guix builds the system, and requires code changes to 
Guix itself, not just to the `configuration.scm`.

The code changes enable:

* `/home` on ZFS.
* Allowing you to put any filesystem inside a `zvol` and declare it in 
`file-system`.
* Assurance that by the time `file-systems` is started, even ZFS automounts 
have been mounted; important if you are starting a Shepherd service that has 
been configured to access filesystems (i.e. all the important ones).

The modifications in the previous email work only in `configuration.scm` but do 
not allow the above.  I think `/home` on ZFS is an important target to have 
(it's what I wanted for my server) at least, but requires changes to how other 
services in Guix System are built anyway.

Thanks
