-According to the FHS, the /usr/include/linux and /usr/include/asm should be
-actual directories, not symbolic links to the ones belonging to the current
-kernel. The major advantage is that programs will compile with the headers glibc
-was compiled with, and this may prevent some compiling hell. Until now, in all
-of LFS' history, no compiling problem has been reported by using symlinks. So if
-you're tight on space, we recommend using symlinks. But if you want to be FHS
-compliant, replace the two last lines from the commands above with those:
