Dotfiles in Version Control

Version-controlled dotfiles are shell, editor, and tool configs kept in a git repo so a machine can be rebuilt from a known baseline. We assess the practice: high value for solo reproducibility, but team standardization and secret hygiene need clear rules before adopt.

Blurb

Dotfiles are plain-text configuration files for Unix tools, typically stored in a home directory and named with a leading dot.

Summary

What it covers: .zshrc, .vimrc, Starship, tmux, Homebrew Brewfile, and similar personal setup committed beside a README and install script (or Declarative IaC-style bootstrap).

When to use: you rebuild laptops often, want the same shell aliases everywhere, or document “how your machine is configured” for yourself.

When to skip: orgs that mandate MDM-only laptops with no local customization; shared secrets in dotfiles (use a secrets manager instead); duplicating what Nix/Home Manager or a golden AMI already provides.

Pairs with: private repo or public repo with a secrets scrub checklist; symlink or copy install script; optional chezmoi/yadm if dotfiles span multiple machines.
