+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.
