# Building reproducible Emacs Saturday, Nov 28 2020, 11:24 AM - 11:44 AM Andrew Tropin It's not always easy to take part of someone's configuration and make it work, it's almost never easy to move your configuration to fresh OS installation or hardware. Not sure that this snippet is enough to make package work? Forgot to install ripgrep in your system for rg.el? Got a broken version of package on package-install? There is a way to make an Emacs configuration reliable, composable and self-contained. It's possible to freeze package versions, create systemd unit for emacs daemon, maintain system dependencies and package subconfigurations in one place with one tool. The talk explains how to leverage the power of nix package manager and use-package to make pretty good emacs configuration. There is a stream record on the same topic: . It lacks few interesting points about composability of such configuration approach, but already have enough interesting information. The talk will be a little more structured and more Emacs-users oriented. Back to the [[schedule]] All times are approximate, and we might shuffle talks around as needed. Please check a few days before the start of the conference for instructions on how to watch and participate. See you then! [[!meta title="Building reproducible Emacs"]]
