On optimizing Linux boots: “The X Window System runs the C preprocessor
and compiler on startup, in order to build its keyboard mappings.”
And that [gulp … hrullphh] is all you need to know about X [grwawwwlphh!].
Later in the article: “X is still problematic. ‘We had to do a lot of damage to X…’ ”
I mean, how could they tell?
