If you=E2=80=99re running a caching proxy, you=E2=80=99ll need 13G.  Howeve=
r note that
it=E2=80=99s only for one architecture and one revision of Guix.  The total
space needed is obviously a function of time (number of Guix revisions
served) and number of architectures.

You could choose an expiration time in your caching proxy that satisfies
your disk space constraints, though.

Our machines that run Cuirass + =E2=80=98guix publish --cache=E2=80=99 need=
 roughly
41+13G since they contain both /gnu/store and /var/cache/guix/publish.

HTH!
