You are right in one way. But as an OS vendor company we will definitely
include this patch in our distribution. This incident has been reported
many a times and its a pain to see the image not boot up, throw up an
error, with the user having to search the work around on the web. What
we are trying to do is save all that trouble. If it can be fixed why not
fix it.
