I've prepared a test ISO image of the new BSDInstall installer for sparc64, which can be found at: http://people.freebsd.org/~nwhitehorn/bsdinstall-sparc64-20110215.iso.bz2 It works fine on my Ultra 5, but I'd appreciate wider testing on sparc64 (as well as general feedback) before we begin integrating this into the build infrastructure. -Nathan
