Do you mean more disk space?
No I mean what I say though to build packages like webkit and libreoffice you DO need lots of disk IN ADDITION TO lots of ram.
How do you build on the device with more RAM when the RAM is built in to the chip?
Debian build their packages on boards that have the arm architecture but have far more ram than the Pi. You can find a list of debian armel buildds at https://buildd.debian.org/status/archit ... hp?a=armel
(look for the line titled "Restrict on buildd:") and then look them up in the debian machines database at http://db.debian.org/machines.cgi
if you are curious about exactly what machines they are using.
You will be able to build most stuff on the pi, it's just large C++ apps that are likely to be a problem.
As to the Debian image, I can't find grub or the kernel, for that matter. They don't appear in any of the usual locations (but as I said, I haven't seen a Debian ARM build before).
Arm is a lot messier than PC architecture and boot details vary hugely by device.
I don't suppose anyone has published docs on how the RPi actually boots, have they?
How the pi boots has been discussed here at length but roughly speaking the GPU boots first and then loads the kernel. The GPU firmware, boot configuration, kernel and initrd are all loaded off a FAT partition at the beggining of the SD card.
Currently the Pi debian image will not be using a debian supplied kernel as debian do not yet (and may never) provide a kernel that supports the Pi. This is not an unusal situation for arm devices because there are so bloody many different ones out there.
