Making package builds deterministic

[Matthew Jordan]

Good Day everyone,

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

================================================================================

$ export GUIX_BUILD_OPTIONS="--keep-failed --verbosity=3"
$ ./pre-inst-env guix build --rounds=2 address@hidden &>/dev/stdout 
&>${BUILD_LOG}

...
result of ‘/gnu/store/y89n1idbjpq0hhqjpg82mw6bd1llnl21-go-1.4.3.drv’
differs from previous round; rejecting as non-deterministic
@ build-failed /gnu/store/y89n1idbjpq0hhqjpg82mw6bd1llnl21-go-1.4.3.drv
- 1 result of ‘/gnu/store/y89n1idbjpq0hhqjpg82mw6bd1llnl21-go-1.4.3.drv’
differs from previous round; rejecting as non-deterministic
note: keeping build directory `/tmp/guix-build-go-1.4.3.drv-0'
guix build: error: build failed: build of
`/gnu/store/y89n1idbjpq0hhqjpg82mw6bd1llnl21-go-1.4.3.drv' failed

================================================================================

What I would like to know, is there a way to have two build/output directories
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,
