Good Day everyone,

After running the following commands I got some output at the end
indicating non-determinisim.

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=

$ export GUIX_BUILD_OPTIONS=3D"--keep-failed --verbosity=3D3"
$ ./pre-inst-env guix build --rounds=3D2 go@1.4 &>/dev/stdout &>${BUILD_L=

=3D=3D=3D=3D=3D

What I would like to know, is there a way to have two build/output direct=
ories
to compare (maybe with diff or some other tool). Basically I'm just
trying to identify the files causing the non-determinisim.

Any information would be appreciated.
Thanks in advance!

Sincerely,
