/usr/kvm/sys

On Solaris 1 systems, you will find another directory that contains header files. This is the /usr/kvm/sys directory. The header files contained here are used specifically during the build of a new executable kernel and, with a few exceptions, are the same files you would find in the /usr/include/sys directory.
