Guix system on AQEMU HD fills

[Brian O'Keefe <okeefe@cybermesa.com>]

Hello

This is very probably simple but not for me. I've been installing and 
reinstalling the latest GUIX OS in AQEMU. Aside from tweaks needed to 
conform to the install instructions everything is mostly good. But 
that's after 8 install attempts! However, yesterday I got a warning from 
my Ubuntu host that my HD was dangerously low. So I jettisoned as much 
data as I could in a few minutes, including my several VMs. I saw that 
my ~/.aqemu folder was packed and the culprit was the virtual GUIX 
machine which had far exceeded its 25GB capacity. I managed to regain 
48GB by deleting it and other data. I am wanting to run GUIX as a VM but 
this seems to be an issue as I just reinstalled it and just running a 
"reconfigure" to set my PATH I see that the VM has already swelled to 
over 20GB. It also seems that with each "guix pull" or "guix refresh" or 
"guix upgrade" more and more data is being stored. When packages are 
refreshed or repositories updated and then the system upgraded, aren't 
the old packages overwritten or dumped, or something? It looks like my 
new VM HD of 30GB will soon be filled. Why that affects my host OS, I 
don't know. I'd think that the host would just stay at whatever storage 
it has left if the VM HD fills up.

Many thanks!!
