Both use the ‘add-to-store’ RPC, so both have equal chances of failing. Note that, fortunately, fixed-output derivations (‘guix build -S foo’) do not use ‘add-to-store’. In general, except in the case of ‘guix download’, ‘add-to-store’ is only used with small files like when adding .scm files to the store, etc. Ludo’.
