[fedora-arm] Cross-compiling, building ARM RPMs

Hi, I would like to create a rootfs image with a minimal set of software (busybox) for a target ARM device. Given a toolchain for the target hardware, what is the recommended method to cross-compile, build RPM packages? I guess, the cross-toolchain can be packaged separately for x86. Appreciate any inputs, Thanks! SK -- Shakthi Kannan http://www.shakthimaan.com
