It isn't the *only* thing (the qt4 package going through the Extras review process at the moment springs to mind as an example I came across yesterday) but packages have to be carefully designed to be parallel-installable by using version/release numbers in all pathnames to avoid pathname conflicts. For most packages containing binaries, this isn't even possible. The kernel (and associated modules) are certainly the only things commonly parallel-installed. Paul.
