[1] Poudriere already has a -S flag to avoid rebuilding things when a run dependency changes. I see there is ongoing work related with this flag, but it should be usable most of the time, although it exposes to some of the same risks that building manually causes. [2] DISLAIMER: Everyone is free to manage his own machines as he sees fit, there is really no sanctioned way to do that, and building ports on live machines is supported, and I have fixed bugs in the ports I maintain that failed to build properly in such an environment, and will keep doing that to the best of my abilities. But I also must state that doing things like that is a way to look for unnecessary trouble. Poudriere is resource hungry, because building software is resource hungry and will get even hungrier. I started computing on a Spectrum 48K and am still baffled by how we got to a condition where 48K is not even enough for a simple configuration file, but here we are.
