I just keep upgrading to the fastest CPU I can possibly justify to avoid
losing focus; it goes fast with 8 cores. I was trying to demonstrate
that peg makes this very high level now, and I was more jousting at the
idea that everyone should bother to write their own individual reinstall
script.
The peg code makes it easy to assimilate whatever other neat
optimization ideas one might come across. I just pushed an update out
that absorbed this one, so now if you do:
stop
peg rebuild
It uses the install-bin trick you suggested. It even does a couple of
sanity checks so that it will probably fall back to a regular build if
it doesn't look like you have a good install and binary tree already.
Maybe I'll make a "reinstall" alias that does this combination next.
I don't expect to improve your workflow. But people who haven't already
invested a good chunk of work in automating things already will probably
take some time to catch up with where peg puts them on day one.
