Maybe I can convince Colin that, until full cross-compiling is available, we sparc64 folks would settle for slightly-delayed binary security updates (instead of never getting them at all). It's the very fact that we're running on slower hardware that makes freebsd-update so attractive. I'd still like to see what a quad Ultra 80 can do, though. :) Who has access to one of these? Chris, did you do any of the other things that the handbook 'Rebuilding "world"' section suggests -- noatime /usr/src, async /usr/obj, etc? Also, are you tracking 6.2-STABLE, -RELEASE, or something else? If -STABLE, as of when? Over time, these data points may be relevant. >> Is anyone interested in tracking buildworld times for various FreeBSD >> versions and architectures?
