permissions inside linux-2.6.0-test6.tar.bz2

[Delian Krustev <krustev@krustev.net>]

First excuse me if this has already been posted but a quick search
showed me it hadn't. The problem is trivial and it should have been
resolved if it has been reported.

Here it is:

# tar xjf linux-2.6.0-test6.tar.bz2
# find . -not -perm -444 -exec ls -al "{}" \;

So, these files are not world readable as they should be.
I bumped into this while trying to compile the kernel from user.
Anyone trying to do so and trying to use one of these files is
affected.
It's really a matter of running chmod -R but there might be some cases
where this is not possible.

One more thing I want to recommend. Please use the tar options
--owner 0 --group 0 when creating the archive. The uid/gid 1046
combination might already be present on the system(or appear in
the future) and might bring security risks for the unwary.
