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
total 88576
-rw-r--r-- 1 root root 1057 Dec 1 03:23 anaconda-ks.cfg
-rw-r--r-- 1 root root 13205 Dec 1 03:23 install.log

[root@localhost root]# cat /usr/src/pax_global_header

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??!!
Kernel tar-archives created by git contain an extended header with the git
commit ID that was used to generate the tar-tree. If your tar is older
than 1.14 then this extended header will be extracted as a regular file
called pax_global_header. Patches should never be generated against this
file, so it should be listed in dontdiff.
It sounds like a file you can safely ignore.
As for your second question, if the documentation tells you to not overwrite a pre-existing file, I would believe it. You even quote a very pausible sounding reason. Personally, I would follow the instructions. But it's your system.
Cannot present unpresented disks back again. On a test server tried this as a solution "multipath -r" and it worked. Too worried to try it in production before I know all the information.
Any info would be appreciated!
