Diffrence in yum update
 

Hi

I did a yum update with the same repository.

on the one x86_64 system the kernel shows as 2.6.18-194.26.1.el5.

On the other system it shows as 2.6.18-194.el5. Both are vm systems on the same box.

Why did this happen and what is the diffrence between the two kernels?

Both were updated at the same time?

Hi Yes

i have noticed that before the update the kernels were.

2.6.18-128.el5

2.6.18-128.2.1.el5
respectivley

Ok this is what i have found.

if you do a yum update on a system with 2.6.18-128.el5 it will only update to 2.6.18-194.el5.


Check out the grub.conf

I took the repo from the system with 2.6.18-194.26.1.el5 and applied it to the system with 2.6.18-194.el5 and when doing a yum update it says no updates to be applied.

I took a system that has the 2.6.18-128.el5 kernel and did a yum update with the repository from the system with the 2.6.18-194.26.1.el5 kernel
and gave me the grub as above as well as the kernel 2.6.18-194.el5.

if i do an update with the same repository files on a system with 2.6.18-128.2.1.el5 kernel via yum . It updated it to 2.6.18-194.26.1.el5 kernel

now why is this?
