Please note that this is NOT about the 256 MiB OneNAND. I could start saying that end users won't fill their 256 MiB partition, that optifying packages is very easy, and there's more reasons to why you can't drop Debian .deb packages in the N900, but then this thread would convert into yet another /opt discussion and there's been too many of them already. So please don't, and let the discussion of the ext3 partition keep on.
