Whoa, why? Or, more specifically, why are you not using migration from a prior Mac or from a Time Machine backup? The ease with which a Mac user can be up and running on new hardware is, to me, one of the larger advantages of the platform. I know, this being HN, that you likely have a number of FOSS tools installed; are they somehow not getting picked up properly by migration & backup?
True story: we were robbed in 2012, in a quickie smash-and-grab through a rear patio (glass) door. They were in and out in maybe 1 minute, and took only what they could see from the yard -- which included my Macbook Pro.
We're well insured, so I went and got a new one the next day, plugged it into my Time Machine drive, and went and had lunch. When I came back, my new machine was ready to go -- all my apps, all my data, and even all my app windows were restored.
