@untsuki Oh, believe me when I say, there's a LOT of stupid legacy GNU is carrying around.
POSIX in general also. I love it, but there's a lot of stupid legacy in there still, back from the times when computing was done using typewriters and stuff.
And it's not like it's much of a choice. The thing about stupid legacy is, when you change it, something critical breaks very fucking swiftly. Everybody hates it, but that's why it's still in there.
