Ken, does this mean you use, e.g.,
--enable-kernel=3.4.4?

So, SRCD had linux-3.0 but your system was built with
--enable-kernel=3.2?

You know, I recently cloned a VM LFS system to another hardware, so
these questions interest me very much, particularly, I agree very much
with your last sentence about "rescue path".
