@@ -659,6 +659,8 @@ If the kernel being built for does not match against this regular expression (or
 does not the satisfy the constraints of any other
 .B BUILD_EXCLUSIVE_*
 directive), the dkms build will error out with exit code 77.
+Note that dkms autoinstall will ignore this type of error condition and simply
+skip the respective modules.
 For example, if you set it as ="^2\.4.*", your module would not be built for 2.6
 or later kernels.
