Package Management

I think Pacman might be a good choice but maybe it would be possible to have chapters for Pacman, dpkg, and RPM, and the user could use the chapter pertaining to his choice of package manager.  I think that all three PMs use DESTDIR, so the package manager is transparent to most of the build process.  It would only be visible when the PM is used to create the package.  

DIY Linux is set up to allow the use of package managers and uses DESTDIR, although Greg does not mandate any package manger.

And wouldn't it make it possible to upgrade the toolchain without rebuilding LFS?
