guix pull avoidance

[Vincent Legoll]

Hello,

when one does guix pull, it is done only for that user, another one
doing it subsequently (or at the same time) is going to download
and compile the whole (identical) thing again, is it possible to switch
a user to a previously dl'ed revision, like just changing a symlink in
~/.guix-profile to point to /gnu/store/*-guix-latest, or something like
that ?

I have seen suggestions about using git as a backend for guix pull,
but until that happen is there an easy way to get the same thing done ?

Thanks
