Finally got the Sheeva booting and got a base Debian installed and I'm coming to the end of these noteshttp://www.openplug.org/plugwiki/index.php/Installing_Debian_To_Flash#Convert_internal_flash_root_partition_to_UBIFS
and I've got to this bit "Clone USB rootfs to internal flash"
Reading through this it reformats the internal 512M disk and then mounts it on /mnt, it then binds / to /tmp/rootfs to remove unwanted device files etc and copies all the files from /tmp/rootfs to /mnt.
Is this really the right thing to do, to copy all the files from the root on the SD card onto the internal disk including all the files in /var/cache/apt and any other bits that have been left around from the setup that aren't needed any more.
And what does this mean for the SD card that I installed on to, this now seems irrelevant as it isn't being mounted any more and isn't being used. Isn't the point of installing to SD card that you are running from a nice 4G card rather than the internal 512M.
I can kind of understand what is going on but it seems either to be missing an explanation as to why the way it is being done is better than leaving it on the SD card or some explanation as to what the role of the SD card is after all this or even why use the SD card at all, why not just install to the internal disk from the start?
