He's not dead, he's resting
Good News Everyone!
Good news everyone! Portage no longer corrupts mtimes when merging, which hopefully means the Council won’t force us to screw up EAPI 3 any more. Now Portage will either exactly preserve mtimes to the degree supported by the filesystem, or drop the nanosecond part to 0 (which some filesystems do anyway, so programs have to be aware of that possibility), which is what the sane people have been after all along.
Next up: see how long it takes everyone to see the light and realise that the package mangler should only be preserving mtimes that are after the start of the build process, so you don’t end up with lots of files with mtimes in the past getting merged.
