Hmm, but wasn't that the case for a long time, I remember failing to do a full rebuild of FreeBSD on the Mac a year ago, after lots of hand waving and hair scrathcing. I gave in to do everything on VM's running FreeBSD for now. Although now with clang/LLVM in the picture on FreeBSD too, I would probably have a better time now > It also means that people can do things like have out of date builds > of things like bootloaders, mkuboot/mkuzimage, etc. At least all the parts you have to worry about are in one place, somebody has to look after the system in some way Werner > That's why I'm kind of a bit worried about this trend. > > I'm likely going to go the opposite way with my stuff.
