Hi Kenneth, Did you know that, when developing user-space applications, there is almost *never* a need to reboot to use the i386 and x86_64 versions of FC-4? On x86_64 hardware, you can readily create chroot-ed environments by hand using old tricks such as: http://www.tldp.org/HOWTO/Multi-Distro-Dev/ that will allow you to build i386 applications within "pristine" i386 FC-4 installs. Neat, huh? The "mock" ("yum install mock") and "mach" programs http://thomas.apestaart.org/projects/mach/ are two examples of convenient setups for building RPMs that take advantage of this neat chroot feature.
