I am attempting an offline build without success. I have a Guix 1.2.0 node with internet access on which I download sources with transitive dependencies:
$ guix build --sources=transitive tzdata > ~/transfer
I then copy the files as root to a Guix 1.2.0 node without internet access (only local network access):
# cat /home/<user>/transfer | xargs -n 1 -I{} scp -p {} <ip>:{}
I then attempt to build on the offline node:
$ guix build --no-substitutes tzdata
Guix starts downloading and the transferred file is gone! I'm lost as to why a new download attempt is made as the file data and timestamps match the original server.

The following derivations will be built:

Building on the original, internet-connected server no re-download is attempted, though additional packages not included in the transitive sources are requested.

If there is a better way to setup / configure / execute offline builds please let me know!
