Grub/Lilo ???
 

I have to reboot a couple of servers, this because of a kernel upgrade.
But does anyone know, how i can see(before booting!) if the redhat servers use grub or lilo to boot from?

If the computer uses LILO then just before boot menu appears you can see for a shorttime the text LILO . if you press pause then boot menu doesnt appear. Same is the case with Grub

To make a change to the correct config file before rebooting?
When I used 'dd' to make an image of my boot sector (dd if=/dev/hda of=mbrread.img bs=512 count=1) and opened the file in a binary editor I see the word "LILO" on the first line. I use LILO.
You would then know to edit and run LILO rather than Grub.
Am guessing vise-verse would work.
Good Luck.

Ok, thanks.
I will give it a try tomorrow.

(The problem with the first reply is that i can't just boot the servers because i can only have a maximum downtime of 3 minutes.)

You could also try the easier 'which lilo' and 'which grub' (as root) to see what is installed.
There has got to be an easier way, but I am not familar with Red Hat configuretion tools or how you are able to access your servers.
