The big deal is Kernel is the most important update file IMHO. Because last time at another server i tried to update kernel by same method. And it said it failed to find template for Kernel or something like that. As a result my server didn't boot up and i had to request KVM and load older kernel
I am not sure if it will give same error this time but is there anything else that i need to do after kernel is updated except rebooting?
edit : i just run /scripts/upcp and it updated all of the programs except kernel-pae. Now it says
Dependencies Resolved

You should be fine then.
You can also setup grub to reboot into the older kernel if the new one is no good (i.e. panics). Check the grub manual for details (info grub).

| Posted by bonjurkes, 07-07-2008, 07:12 AM | | i guess i messed up my server again. I said yum update, and it said installation completed. It downloaded new 2.6.18-92.1.6.el5PAE kernel files to /boot folder and now grub is like
but i can't connect to my server via ssh

| Posted by bonjurkes, 07-07-2008, 08:24 AM | | I got an answer from my dc, they say the reason is because the onboard network interface aren't directly supported for the new kernel that i have installed.
