Hi Guix,

I'm using guix from commit: ec4c404c0575b340a04b3922fb828ac5417832dd

I want to create a vm-image with a btrfs filesystem. Following the manual
for Invoking guix system
ran:

`guix system vm-image --image-size=120GB -t btrfs vm-config.scm`

with the operating system config below.

It produced a working vm image. However, the root file system was ext4.

Is this supposed to work, or did I misunderstand the documentation?

In an ideal world, I hope that this would work, but if we don't support it
yet, I think that we should clarify the documentation, and make guix
system vm-image error when passed a file system type it doesn't support.

Best,
Jack
