I didn't think I needed i386 personally. In fact due to this thread I removed many
i386 packages left on my machine. Just today I plugged in an 'IronKey' device. Its
an encrypted USB drive. When plugged in a read only like mount is mounted, like a CD. On
it is a binary to unlock the device. It no longer works, I get an "unable to execute
./ironkey: No such file or directory" likely because I'm now missing the i386
libraries or other requirements.
