I am familiar with Debian based distros and now I have to administer CentOS machines. I have two CentOS 4.4 machine and I both applied
on them and they are both (lsb_release -a) 4.9 final now.
However when I looked the kernel version
One of them
Machine A: 2.6.9-42.0.3.ELsmp Machine B: 2.6.9-42.0.8.ELsmp
Then I copied Machine B's CentOS-Base.repo file to Machine A then copied B's yum.conf to A and I retried but yum upgrade but A's kernel version is still same. What can I do? What do I miss? Thanks
