mysterious grub

I've been recompiling my kernel, and getting some strange errors when trying to load newer modules. I think this might be due to a grub problem I've been having. I don't remember how I installed grub earlier, but it must have been some sort of automatic thing. Any changes I make to /boot/grub/grub.conf don't show up at the grub screen... only the same thing I've seen since I reinstalled everything at the beginning of the semester. I tried uninstalling grub and then reinstalling. Where should I look? Can I switch to Lilo to get around this problem? I really have no idea what config file grub is looking at. I've done a search, too, and haven't found any other grub stuff.

On what partition is your MBR? I guess it takes another grub installation on another partition. Normally every change to grub.conf gives direct result.

Do you have a seperate boot partition that you didn't mount before changing grub.conf?

I'm having the same problem, but I think I may have solved it. I just updated my kernel to sys-kernel/suspend2-sources-2.6.14-r7, so I needed to change my grub.conf. But none of my changes would show up on boot. And no, I didn't forget to mount /boot before editing it.

I discovered that in addition to the normal /boot/grub/grub.conf on my system, somehow I got a /boot/boot/grub/grub.conf. I'm going to copy my /boot/grub/grub.conf over the new mysterious one and reboot, to try and confirm my suspicion that grub is getting its configuration from the new file. I'll report back in a minute, after the reboot.

Success! Putting my desired configuration in /boot/boot/grub/grub.conf made my changes show up on boot. But I'm still left with a few questions, that I'll try to answer soon:

How did I get a /boot/boot/grub/grub.conf?
Why does grub use it?
If I delete it, will grub revert to using /boot/grub/grub.conf?

I have a vague memory of seeing a symlink in /boot that linked to its parent directory, such that you could descend forever into /boot/boot/boot/boot/boot... You get the idea. Maybe this grub problem is the reason for such a symlink. I'm going to try the following:
