I am not familiar with the installation process.  I miss where this
first “guix pull” writes:

 - the cached checkout
 - the store items

I am expecting that the first “pull“ writes both on the target.  If not,
i.e., it writes on the installation target, yeah it could be improved. :-)


From your initial message, my understanding was the first pull writes:

 - the cached checkout in /root/.cache/guix/checkouts
 - the store items in /gnu/store

then your second pull writes:

 - the cached checkout in /home/user/.cache/guix/checkouts
 - the store items in /gnu/store

Therefore, the repo is cloned twice and derivations are also computed
twice; but it seems hard to avoid by design.

I do not think the checkout is in the store but in
“/root/.cache/guix/checkouts“, I guess.
