I wonder if I need to restart it one more time since it now has all the updates installed, maybe it was the old kernel still loaded which panicked when I restarted just that once after updating?

Hi,

You need to update your bootloader possibly with the new kernel and configurations. If not then you will default to the old one.

Doesn't it do that automatically when I update the kernel with up2date? I thought it was supposed to but I don't know.

Hi,

I'm not sure about RH. But I would make sure, it's easy to confirm to be safe.

How would I even know if it put the new version in there, or if its just the same old one?

Sorry, I've never done this before.

Hi

Look at the '/boot/grub/menu.lst' or the '/etc/lilo.conf' whichever is being used. Or look at the time stamp for the files via the 'cli' with 'ls -l or ls -al' to get a long list;

Code:

~#ls -l /boot/grub/menu.lst

or

~#ls -l /etc/lilo.conf

Either of the above will show the time stamp for the bootloader conf.

Edit: You should take a look at some of the references that I linked earlier if you are going to be maintaining this rig.

I have the menu.lst which points to grub.conf that was updated this morning, so that must be it.

Here's what the file says, looks like it has two listed, does it boot them in order in the file, so the newer one is booted first?
