1. What is the target system(s) you're using? I for one have a very vague

This was my question too. I attended a talk by Deepak Saxena a month
ago and it looked like there's no clear leader anymore, like Netwinder
used to be. What are these RPMs for? OpenMoko? Palm? Are these systems
even binary compatible in the user mode?

All the packages are built using ARMv5 soft-float with EABI. That provides a good baseline for most ARM boards/devices. To be useful, we will need to build for different CPU variants in the future (e.g., ARMv6, with or without VFP, XScale, etc.) that make use of the optimizations specific to the CPU variant.

The other part of this is the kernel. Unlike x86, it is impossible to build a single kernel that will be of much use. So, either we completely punt and not build the kernel image, or we build multiple kernel packages -- one for each target board.

The ARM distro will also be unlike x86 distros in that it wont be of much use to have ISOs. Instead, you probably just need the RPM package repository as a good baseline for it to be useful (along with the tools and docs to use the packages to create custom root file systems).
