I tried a guix pull as a user and as root on both machines.

Now on both machines guix and guix-daemon used are the same, here are 
both paths:

/gnu/store/m79ld7h62wjbx6kc2jip73lmh8lfc8qs-guix-command
/gnu/store/z642sncd5jgj4bc3p18rdqwdkq30p833-guix-daemon

When I try a guix copy the requested hash is still different from the 
one on Machine_A (and it wishes to recompile it):

Machine_B # guix copy --dry-run --from=Machine_A bazel
The following derivations would be built:
   /gnu/store/0lscmi07b2y0aw6hscbgm2h7nqwc6sb1-bazel-6.4.0.drv
/gnu/store/gssvcsrhq6j2pifavjzw00h8wqlx05km-java-commons-compress-1.21.drv

/gnu/store/ggg0r1jxp8vvk3sfva6kgc0vsrrlzzb1-zipbomb-bazel-6.4.0-dist.zip.drv
681.5 MB would be downloaded:

What am I missing ?

Thanks for your help
