This patch should be applied on platforms which support kernels < 2.6.27 and need udev-compat package.

It should be applied after:
sed -i "s:/sbin/udevd:\$UDEVD:g;s:/sbin/udevadm:\$UDEVADM:g" init

It has not .patch suffix, because such files would not be copied to
WORKDIR and cannot be selectively applied on another source file.
