More specifically, Portage. I know use flags and “optimization” are all the hype, but really, would the average user even see a benefit from customizing all their use flags? Especially a benefit that compensates for the constant compilation?
I installed it once to help grow my e-peen, but immediately switched back to Arch after watching my system compile.
Those who daily drive it, do compilation and use flags annoy you, and do you see any real benefit?
You misunderstood. The configuration is one time. Updates and patches gets configured according to your configuration.
FYI, The updates you get are also pre-compiled by the distro team, and are compiled with generic flag to ensure compatibility.
