This has been discussed on IRC and on guix-devel mailinglist
but so far I haven't seen a formal bug report to make this
visible.

I can't find the right threads or timestamps for this
bug, so take it as is and extend with facts.

At the moment of writing, guix pull has the minimum
requirement of 3 GB RAM.

Before this started, I was able to run Guix on as
little as 512MB RAM.

People are currently finding out about this bug
the hard way, so we should point this out. Didn't
really happen so I guess someone is working on this
already.
