What's the possible issues and impact of building the F-15 build chain on F-13 vs building on a F-14 toolchain like mainline F-15 on x86 would have been? > Once I get some feedback, I'll be updating the wiki, along with some > more F-15 goals and (hopefully) generally useful stuff. Thanks for kicking off this conversation. Its been something discussed on irc and other channels. I would like, if its possible, to get to a reasonable decision ASAP so its possible to get what ever changes are necessary into dist-f15 final (simply so we follow F-15 release as close as possible) for the rehat-rpm-config or what ever packages are needed to compile and support the HW platform including things like what ever the rpm naming ends up being.
