file "pax_global_header" means what?
I'm using Red Hat 9.0, the kernel is 2.4.20-8,
I want to update the kernel ,
go to www.kernel.org and then download the linux-2.4.37.7.tar.bz2
to /root
Code:
 
[root@localhost root]# ll

[root@localhost root]# cat /usr/src/pax_global_header
52 comment=c296c56a03b2629b05bbe21cd5d4a0bb750d812c

my first question is:
what the file "pax_global_header" is?? It's for what?

my second question is:
under the linux-2.4.37.7/, there is a README, I looked into this README,
it mentioned:
Code:
INSTALLING the kernel:

 - If you install the full sources, put the kernel tarball in a
   directory where you have permissions (eg. your home directory) and
   unpack it:

        gzip -cd linux-2.4.XX.tar.gz | tar xvf -

   Replace "XX" with the version number of the latest kernel.

   Do NOT use the /usr/src/linux area! This area has a (usually
   incomplete) set of kernel headers that are used by the library header
   files.  They should match the library, and not get messed up by
   whatever the kernel-du-jour happens to be.


but in my mind , the palce to store the source code is usually /usr/src, so i unzip the .tar.bz2 to /usr/src.
so, it true or important that Do NOT use the /usr/src/linux area??!!
