This may be a silly / obvious question. I'm very soon switching from 32bit to 64bit Ubuntu on my dual core intel box.
Are all packages in Ubuntu 64bit compiled for 64bit, or just some of them - i.e.: applications that actually take advantage of the 64bit processor. In other words - is there any point in my doing an apt-on-cd backup of all the updates I've installed to Ubuntu 7.10, or will every package have to be downloaded again as a 64bit version anyway? Thanks.
