Hi,
I was updating Guix today with the option rounds=2 and I hit an error
with mpv having different outputs everytime it was built.
The message is this:
building /gnu/store/qkmylc2cd950kf4zk8y3ay0hpwcvjpvr-mpv-0.32.0.drv...
\output ‘/gnu/store/q71zaxglbwmw3z4r1a3jmf1mgwrpmv4c-mpv-0.32.0’ of
‘/gnu/store/qkmylc2cd950kf4zk8y3ay0hpwcvjpvr-mpv-0.32.0.drv’
differs from previous round

And my system is this:

Can you please tell us what files differ when you build mpv a second
time with “guix build --check -K --no-grafts mpv” and compare the two
output directories? Perhaps there are obvious patterns that could give
us a clue as to what causes the differences.
