DragonFly still lacks binary upgrades which makes upgrades on older computers a real PITA. While dealing with this in the last few days an idea popped into my head for at least partially resolving this: upgrade packs. These are basically source trees on which buildworld and buildkernel has already been performed. If one tar's these up and shares them, the end-user would only have to download and unpack them, followed by an installkernel/installworld/upgrade sequence. Were these pulled from git, later updates for the branch from which the whole thing was generated could easily be pull'd and quickworld/quickkernel could be performed (I am talking about release branches in the first place). This way, binary upgrades would partially be resolved, but this needs a little extra storage space on the mirrors, however this should be no big concern since my copy here is ~700M uncompressed.
So the whole thing: -pull from git - make buildworld - make buildkernel - tar up - share Opinions?
