For the browser, I use a Firefox login to sync my work machines (laptop + desktop at home.) I’m still enough of a neck beard to not want this for my personal stuff, but for work it’s a dream come true. For command line, all the tools I use have the equivalent of “source other/file” in their config language so all my dotfiles begin with a source line that sets up my sensible defaults, and then local changes come afterwards. For example: # ~/.bashrc source ~/.config/dotfiles/bashrc # Local stuff GITLAB_TOKEN=… .config/dotfiles is a git repo. I have very few local overrides, there’s no install step needed other than a git pull, and no mucky symlinks. The initial setup is a script on my website that I curl-pipe-to-bash on new hosts. For my dev environment I have a script that builds a dockerfile that makes an ubuntu:jammy and installs 30 Debian packages, 10 Python packages, and two locales that apparently I can’t live without. When you run it, it bind mounts $HOME into the container and then cd’s to the directory I started in. With one command I can go from ~/projects/foo on my machine to ~/projects/foo in the container with all my favourite tools. You can bind mount SSH_AUTH_SOCK and your X11 Unix socket too to run a bleeding edge copy of Xeyes. Docker on macOS M1 means the same environment in macOS as on my dev servers and desktops.
