azos

azos-core is a git submodule — git add must be run inside it separately from the outer repo

postPatch in Nix derivations: alejandra reformats indentation of multiline strings, which can change effective shell script content

azos/emacs — Emacs-specific gotchas (async-shell-command/pty, org-babel lexical binding)
azos/mail — mu4e/mbsync/msmtp accounts, contexts, bookmarks
azos/hardware-auth — YubiKey U2F login/sudo setup; lauretta's fingerprint reader is unsupported, why, and what would unblock it
azos/todos — open project TODOs
