Considering I never explicitly flashed a kernel to start with (or 
anything else for that matter; my NAND still contains the factory 
default setup AFAIK), yet it apparently booted a qtmoko kernel, I doubt 
I need to do this (unless QtMoko automatically flashes its kernel to 
NAND before first boot or something, which would be *very* strange IMO).

Thank you for the suggestion though, as you said, you couldn't know what 
my setup is like.

Hmm. I'm probably still on the old boot system, and after thinking about 
it, I think it boots the /uImage (without /boot dir) from the (first) 
FAT partition, without looking in /boot on the ext4 partition - while 
the .deb package probably only updates /boot/uImage in the rootfs on the 
ext4 partition, leaving the uImage on the FAT partition alone.

Either way, the new boot system sounds quite nice; if I understand 
correctly from the other email, it completely eliminates the need for 
that initial FAT partition, so that I can use just the ext4 one. :D

This sounds familiar from my GTA02 days, and it does not surprise me to 
hear that it is still the case for GTA04. In fact, it would have 
surprised me more if this had been changed. If/when I install a system 
to NAND though, I'll keep it in mind.
