The people who make the copy rather than symlink for distributions
claim it's required to have same kernel headers as your glibc was
compiled with, but this is nonsense since glibc includes don't use the
kernel headers... Also, doing this makes for a broken
system...consider the case where your glibc was compiled with kernel
2.0 and you want to use fbcon. Oops, there's no linux/fb.h!! 1000l to
whoever forgot to think about stuff like this...
