Re: [Mactel-linux-users] /boot problem

[Jelle De L. <sk...@ki...>]

Ah, I've finally found the problem!
Well, there were several ...

The tutorial on that wiki was actually based on this one:

http://code.google.com/p/atv-bootloader/wiki/InstallGentooVer1

Except they messed everything up. In the wiki-tutorial they were 
installing another kernel, yet they forgot to update the symlinks and 
grub.conf files and such.
I've wrestled with this one for quite a while, I think I'll change a few 
things on the wiki itself to make it work properly :)
