Operating Systems Linux Red Hat [RHEL6]Uncompress vmlinuz to vmlinux Post 302534664 by Chrisdot on Tuesday 28th of June 2011 11:55:46 AM

Thanks fpmurphy for pointing me to extract-ikconfig script. I have found that here:
http://www.kernel.org/pub//scm/linux...tract-ikconfig

I describe a little bit my history.
Firstly I installed kernel-debug package (yum install kernel-debug) that caused files:

vmlinuz-2.6.32-131.4.1.el6.x86_64
vmlinuz-2.6.32-131.4.1.el6.x86_64.debug


to come into being in /boot/ directory.
After fighting with those vmlinuz files (I wanted vmlinux) I asked for help on that forum.
Now I got script and if I run it the output is like:
Code:
extract-ikconfig: Cannot find kernel config.

I may say also, that in /boot/ directory I have got files:

config-2.6.32.131.4.1.el6.x86_64
config-2.6.32.131.4.1.el6.x86_64.debug


If I remove from 'extract-ikconfig' script following line:
Code:
# Prepare temp files:
tmp1=/tmp/ikconfig$$.1
tmp2=/tmp/ikconfig$$.2
#REMOVED THAT LINE: trap "rm -f $tmp1 $tmp2" 0

I got two files in /tmp/ directory.
Output is the same.

Is it something I need?

Thanks

PS. I just need vmlinux to debug kernel module.

NAME
yum-debug-restore - replay Yum transactions captured in a debug-dump file SYNOPSIS
yum-debug-restore DESCRIPTION
yum-debug-restore is a program which takes a gzipped file created by yum-debug-dump and acts on the information about installed packages contained within. GENERAL OPTIONS
--output Output the commands that would be run to stdout. --shell=<file> Output the commands that would be run to a file. --install-latest Ask yum to install the latest version of the given packages, instead of the version that was installed in the debug-dump file. --ignore-arch Ignore the architecture of the packages, so you can "restore" an i386 debug-dump on an x86_64 machine. --filter-types=[install,remove,update,downgrade] Only perform the given types of commands, so you can filter to just upgrades and installs. FILES
As yum-debug-restore uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which repositories to use. Consult YUM documentation for details: /etc/yum.conf /etc/yum/repos.d/ /var/cache/yum/ SEE ALSO
yum-debug-dump (1) yum.conf (5) http://yum.baseurl.org/ AUTHORS
See the Authors file included with this program. BUGS
There are of course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. James Antill 15 December 2011 yum-debug-restore(1)
