Heh. I write an internal developer tool at Shopify that is (somewhat) conceptually similar to vagrant. (https://twitter.com/burkelibbey/status/858013844626649092 https://twitter.com/burkelibbey/status/858013844626649092) Like you, we distribute it as a git repo. We don't use bootsnap with it, but we have a few strategies that give us reasonable times: $ time ./bin/dev help up >/dev/null 0.07s user 0.03s system 98% cpu 0.102 total * We vendor every dependency (and try really hard to avoid them in the first place -- we have 5, only one of which is >5 source files), and prevent loading rubygems. Rubygems takes a long time to load. Our shebang is `/usr/bin/ruby --disable-gems`. * Autoload everything. Our toplevel lib/dev.rb file is a whole-namespace autoload registry. Only a few other constants are defined there. Everything is loaded just by cascading through autoloads. * Defer stdlib requires: We load most stdlib features within the method body from which they're used. Several stdlib features take a surprisingly long time to load.
