OpenBSD (newbie alert, I'm no expert): when following -stable or -current branch in OpenBSD, the documents advise you to keep the source tree for the kernel, the src and the X system in step with each other and to only take ports or binary packages from the appropriate repository. You are also advised to compile the updated kernel first, reboot into the new kernel and then recompile the src and xenocara(X system) trees. So although the individual programs are all separate, they are intended to work together as a whole with common configuration settings &c and the source is kept in a single cvs tree. You can't mix and match (say) an Xorg taken from somewhere else and your own special cat program. My understanding of the systemd project - especially later versions with kdbus in the kernel and udev integrated in along with networking and the console - is that you may need to 'lockstep' your choice of kernel, systemd packages and possibly the DE if using Gnome in order to have a functioning system. I can see advantages in this but it does represent a considerable cultural change in the Linux world which has previously been a little bit like a Lego set. If I have this wrong, please advise and correct.
