Hi,

Note that you may need --no-grafts, otherwise you=E2=80=99re asking for the=
 log
of the grafting derivation.

Apart from that, offloading does =E2=80=9Ctransfer=E2=80=9D logs to the mas=
ter node
(search for =E2=80=98build-log-port=E2=80=99 in (guix scripts offload)).  S=
o the master
node ends up with the build log as it if were built locally.

There=E2=80=99s one exception though: if the thing that was offloaded was
actually already available in the build machine=E2=80=99s store, then the m=
aster
node won=E2=80=99t get any build log.  Perhaps that=E2=80=99s what happened?

HTH,
Ludo=E2=80=99.
