Re: Offline build failure

Hullo Greg,

If there is a better way to setup / configure / execute offline builds

please let me know!

...yes :-)

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

OK.

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>:{}

Now you've basically reinvented ‘guix copy --to=<ip>’, but in a way that won't update the store database in /var/guix/db. I'm afraid that won't work. Guix won't ‘see’ the files you copy to the remote store and will consider them G to be C'd next time you run ‘guix gc’. Or in this case:

Guix starts downloading and the transferred file is gone!

Same thing.

I'm lost as to

the original server.

why a new download attempt is made as the file data and timestamps match

Kind regards,

T G-R

If the file isn't registered in the database, the store item is never considered valid. Guix doesn't (yet) care about the data/timestamps at this point. If there's a reason you can't/won't use ‘guix copy’, you might work around that by copying each file in ~/transfer to, say, <ip>:/tmp/staging (instead of <ip>:/gnu/store), then running ‘guix download /tmp/staging/<file>...’ on the remote host.
