Creating RPM of compiled kernel
 

I have Files & Directories as shown below,


kernel-smp-2.6.39.4-1
|
|- boot
| |
| |-System.map-2.6.39.4-1smp
| |-vmlinuz-2.6.39.4-1smp
|
|
|- lib
| |
| |-modules
| | |
| | |-2.6.39.4-1smp
| | | |
| | | |-Here is all the modules.


Now, I want to create RPM of above data. so, whenever I install Linux, This rpm will install and My older kernel will replaced by newer.
I don't know how to create rpm of above...
I know rpmbuild command, but it requires Makefile and spec file,
I don't know what to write in Makefile and spec file for kernel rpm.


Thanks.

I think you need to use kernel development tools and that will be able to create a package for you

Where is lilo.conf in linux disk image?
 

Thanks for your reply,

I have successfully created kernel RPM, Now I want to add this RPM to disk-Image of linux operating System. so that , whenever I install this modified linux, my new kernel will be automatically installed. and I want to modify lilo.conf, so that, by default this newly created kernel can boot.

I know how to extract and recreate disk-Image, but I can't find lilo.conf from this Image. but I can find lilo.conf after installing linux, I want to modify this file in disk-image before installing it.

For that I have some questions:
-------------------------------

When we installs any linux os, is lilo.conf automatically generates?
If yes, then who generates it?
If no, then where to write lilo.conf in disk-image?


Thanks.

I think that works in the reverse order:
first you choose a distro, usually it has a kernel. You install it together with a boot manager. The boot manager will detect runnable OSs (like linux or windows) and will create config file. Adding a new kernel will lead to a new session (or more) in that config file. Usually during the installation of the kernel the boot manager will be updated, but you can always ask the boot manager to reconfigure itself and you can also do it by hand.

@pan64: Is it possible with rpmbuild in RHEL6?

yes, rpmbuild is used to create rpm

Updating hdlist and hdlist2
 

Thanks for your reply.

Now, I have added kernel-rpm into RPMS directory in my disk-image, but I have to update hdlist and hdlist2, which are in base directory.

If I do not update hdlist and hdlist2, the newly added kernel rpm will not install with the customised Linux os.

So, any idea how to recreate hdlist and hdlist2?

Thank you so much.

I'll try it out. I didn't knew even kernel packages can be compiled like that. So what if I try to sign it with my GPG signature? I mean, is there any legal issue or not.

I have solved this problem using genhdlist command.

Thank you so much for your guidance.
