No-name 1U rack. Pair of SATA drives. 4 gigs of RAM.

I'll have to try this. But it'll have to be some other time. F16 grub2  
barfed and refused to install, when I got around to installing it via PXE.  
The machine survived a reboot, thanks to the F15 version of grub that was  
left intact. Removed grub2, installed F16 grub, applied all updates. The  
reinstalled grub now barfs on reboot with 'Error 16'. Can't go any further,  
so I'm just bringing it up in rescue over PXE, making a backup over the  
network, and I'll have to install everything from scratch. Stick a fork in  
me, I'm done.
