If you created a 25 GB hard drive with AQEMU (that's a QEMU front-end, 
right?), then the `guix.qcow2` hard drive image shouldn't get much 
bigger than 25 GB. However if AQEMU is using qcow2 snapshots, then the 
image will grow as much as necessary to keep all the snapshot data.

Run `guix gc -d` to delete all old generations. You will not be able to 
roll-back the Guix system to a previous generation once you have deleted it.

Yeah, that seems odd. The only thing that comes to my mind is qcow2 
snapshots as I mentioned above.
