Re: [xcat-user] choosing kernel for genimage (xCAT 2.13.4)

Hi David,

 

Do you want to create osimage to use RHEL 7.5 kernel rpms based on RHEL 7.3 .iso?

 

I think you can refer to examples in this doc, if you have problem, contact us freely.

Subject: [xcat-user] choosing kernel for genimage (xCAT 2.13.4)

I am trying to build new netboot images based on the RHEL 7.3 .iso,
while updating only the kernel (to the one released with RHEL 7.5).
I would like to retain the ability to rebuild the original images.
It seems to me that “otherpkgs” is probably too late, as the kernel
and initrd are populated  first.  

If I drop the updated RPMS in /install/rhels7.3/x86_64/Packages
and rebuild the repo, it should choose the newer ones. Then I’d
need the -g and/or -k options to genimage to use the originals.
Does this make sense or is there an easier way?

Thanks,
