[TriLUG] Linux forums other than trilug?

[Tom Bryan]

So, I've posted about this question a couple of times, and it looks like 
everyone's as stumped as I am.  I'm just about googled out.  What other high 
quality (high signal-to-ratio) forums do you all use when TriLUG can't answer 
your question?

In case anyone wants to take a crack at the original question, I'm having 
trouble with grub and a wrong kernel image version number.  I wanted to move 
my root partition, which contains both / and /boot to another hard drive.

That's it.  :-/  I copied all of the files from one partition to another (when 
they were both mounted under Knoppix) and tried to boot.  The file really is 
/boot/vmlinuz-2.4.20-8 when I mount it under Knoppix or my initial hard drive 
(hd0,7).  Grub is the only thing that seems to see all of those (System.map, 
vmlinuz, initrd, etc.) as 2.4.18-3.  Where does it get that number?  If I 
change grub.conf to say that the kernel on (hd1,0) is vmlinux-2.4.18-3, then 
grub will try to boot it, but then it can't find /lib/modules/2.4.18-3/, of 
course.  Ugh!

I'm just about to report a bug in grub because I can't figure out how else to 
determine where 2.4.18 is coming from.
