Ryan Hughes 041f280f68 Document env-bootstrap and first-run in file layout
- Add default/bash/env-bootstrap to the build-time map and a dedicated
  section describing what it sets, who sources it, and the dev-link gate
  on the PATH prepend.
- Drop 'bluetooth' from the install/user/all.sh hardware-quirks list
  (the per-hardware install script is gone now that the wireplumber
  config ships through /etc/skel and bt-agent enables at first-run).
- Add a first-run section listing the post-login steps, including the
  new enable-user-units.sh that defers user systemctl enables.

# File layout
How `omarchy/` is organized and where everything ends up on an installed
system.
## Mental model
Four Arch packages are built from this one repo (PKGBUILDs live in
`omarchy-pkgs/pkgbuilds/`):
- **`omarchy`** — runtime binaries (`bin/`), install/finalize scripts
(`install/`), migrations, themes, and the Quickshell desktop (`shell/`).
- **`omarchy-settings`** — user defaults (seeded via `/etc/skel`), `/etc/`
drop-ins, package-owned system files under `/usr/share` and `/usr/lib`,
fonts, plymouth theme, sddm theme, branding. Carves out `default/limine/`
and `default/snapper/` (owned by `omarchy-limine`).
- **`omarchy-dev-tools`** — just `bin/omarchy-dev-*`. Optional dep of
`omarchy`; installed for contributors, not end users.
- **`omarchy-limine`** — `default/limine/` and `default/snapper/` from this
repo, plus mkinitcpio and limine-entry-tool drop-ins that live alongside
the PKGBUILD in `omarchy-pkgs/`. Owns the boot/snapshot story end-to-end.
Three layers populate `$HOME`:
1. **Seed**`omarchy-settings` ships static defaults to `/etc/skel/`.
Arch's `useradd -m` copies that tree into a new user's `$HOME` at user
creation. This is the only mechanism that touches a brand-new user's home
for these files.
2. **Finalize**`omarchy-finalize-user` runs once per user and handles the
things `/etc/skel` can't do because they need `$HOME` expansion, the live
`$OMARCHY_PATH`, or runtime detection of system state.
3. **Resync**`omarchy-reinstall-configs` is the explicit, destructive
command for an existing user to clobber their configs back to shipped
defaults.
`/etc/skel` only fires at user creation. Existing users picking up new
defaults must use the resync command.

### Why `etc-overrides/` exists
Some files under `/etc/` (`.bashrc` in `/etc/skel`, `nsswitch.conf`,
`security/faillock.conf`, `cups/cups-browsed.conf`, `plymouth/plymouthd.conf`,
`os-release`) are owned by upstream Arch packages, so we can't install over
them via pacman without a file conflict. Instead they ship at
`/usr/share/omarchy/etc-overrides/` and the `omarchy-settings` `post_install`
/ `post_upgrade` scriptlet `cp -f`'s them into place.
Tradeoff: user edits to those files get clobbered on every `omarchy-settings`
upgrade. This is documented in the PKGBUILD.
## Env bootstrap (`default/bash/env-bootstrap`)
Single source of truth for `OMARCHY_PATH` and dev-link-aware `PATH`. It:
- Sources `/etc/omarchy.conf` (written by `omarchy-dev-link`) if present;
otherwise forces `OMARCHY_PATH=/usr/share/omarchy` so a stale inherited
value can't survive an `omarchy-dev-unlink`.
- Prepends `$OMARCHY_PATH/bin` to `PATH` **only when** `OMARCHY_PATH` is
not `/usr/share/omarchy`. On a production install the binaries are
already on `PATH` as `/usr/bin/omarchy-*` via the `omarchy` package.
Sourced by every entry point that needs the env set:
```
/etc/profile.d/omarchy.sh (system login shells)
/etc/skel/.bashrc (interactive shells)
/usr/share/uwsm/env.d/10-omarchy (Hyprland session via uwsm)
/usr/share/omarchy/default/bash/envs (SSH / non-login bash)
```
Idempotent — safe to source more than once in the same shell.
## Runtime finalization (`omarchy-finalize-user`)
Runs once per user. It does **not** copy `~/.config/**`, `~/.bashrc`,
`flags.lua`, or the nautilus extensions — `/etc/skel` already seeded those.
It only does the things `/etc/skel` can't:
- Skill symlinks `~/.{agents,claude,codex,pi/agent}/skills/omarchy`
`$OMARCHY_PATH/default/omarchy-skill`. Symlinks (not copies) so
`omarchy dev link` against a dev checkout repoints them correctly.
- `xdg-user-dirs-update` (Templates/Public/Desktop folded back into `$HOME`)
and `~/.config/gtk-3.0/bookmarks` (needs `$HOME` expansion).
- Sync `XKBLAYOUT` / `XKBVARIANT` from `/etc/vconsole.conf` into
`~/.config/hypr/input.lua`.
- `xdg-settings set default-web-browser chromium.desktop` and
`xdg-mime default HEY.desktop x-scheme-handler/mailto` (XDG-aware paths).
- `omarchy-refresh-applications` (composes generated `.desktop` launchers).
- Sources `install/user/all.sh` — theme, git, mise, keyring, per-user
hardware quirks (asus mic/mixer, framework f13 audio, …).
- On `--first-install`, marks every shipped migration as already applied
for the freshly-created user.
Idempotency marker: `~/.local/state/omarchy/finalize-user.done`.
The ISO calls it as `omarchy-finalize-user --force --first-install` in the
target chroot as the install user, after `omarchy-setup-system` has finished
the root-side work.
## First-run (`omarchy-first-run`)
Runs once on first interactive login, after the user manager is live. Used
for steps that need a running graphical session and/or a working user
systemd instance:
- `omarchy-hook-install post-update install-voxtype.hook` — register the
Voxtype post-update hook.
- `install/user/first-run/enable-user-units.sh``systemctl --user enable`
the shipped user units (`bt-agent`, `omarchy-sleep-lock`,
`omarchy-recover-internal-monitor`). Done here, not at finalize, because
the user manager isn't reachable from the ISO chroot; `ConditionPath*`
in the unit files keeps them inert on hardware they don't apply to.
- `install/user/first-run/gnome-theme.sh`,
`install/user/first-run/gtk-primary-paste.sh` — GNOME/GTK settings that
need the dconf daemon.
- `install/user/first-run/welcome.sh`,
`install/user/first-run/wifi.sh` — welcome and Wi-Fi/update toasts
(waits for a live notification server before firing).
Idempotency marker: `~/.local/state/omarchy/first-run-user.done`. On
failure the marker is not written and the failed step retries next login.
## Root-side install orchestration
`omarchy-setup-system` (root, in chroot) runs target-side setup at ISO
finalization. It sources:
- `install/config/*.sh` — theme links, lockout limits, lockscreen PAM,
powerprofilesctl shebang fix, docker setup, service enablement, firewall.
- `install/hardware/all.sh` via `omarchy-setup-hardware` — vendor- and
device-specific kernel modules, udev rules, microcode, wireless regdom,
ASUS / Framework / Intel / Apple / Lenovo quirks.
- `install/login/*.sh` — SDDM theme/session config.
- `install/post-install/*.sh` — final pacman/udev/localdb passes.
Logging goes to `/var/log/omarchy-install.log` via
`install/helpers/logging.sh`.
## Explicit resync (`omarchy-reinstall-configs`)
When an existing user wants to reset to shipped defaults:
```
~/ ← cp -af /etc/skel/.
```
Replaying `/etc/skel` over `$HOME` is exactly what `useradd -m` does for a
brand-new user, so this one copy resyncs `.bashrc`, `.config/**`,
`.local/share/applications/`, the nautilus-python extensions, hypr toggles,
branding files, and the shipped migration markers in a single pass.
Then it runs `omarchy-refresh-limine`, `omarchy-refresh-plymouth`, and the
nvim refresh. Destructive: existing user files at these paths are clobbered
without backup.
## Quick reference: where does X live?
| Goal | Touch |
| --- | --- |
| Default file at `~/.config/foo/` | `config/foo/` |
| `/etc/` drop-in we own outright | `etc/` |
| `/etc/` file owned by an upstream package | `default/`, then add to `etc-overrides` in `omarchy-settings` PKGBUILD + scriptlet |
| Package-owned system file (e.g. systemd user service in `/usr/lib`) | `default/`, document the mapping in `default/package-defaults.tsv`, then add the `install -Dm644` line in `omarchy-settings` PKGBUILD |
| Per-user file that's static but lives outside `~/.config` | `default/`, then add `install -Dm644 ... $pkgdir/etc/skel/...` in `omarchy-settings` PKGBUILD |
| Runtime tweak that needs `$HOME` or live system state | extend `omarchy-finalize-user`, or add a per-user leaf under `install/user/` and wire into `install/user/all.sh` |
| One-time root-side setup step | `install/config/*.sh` or `install/hardware/*.sh`, wire into `omarchy-setup-system` or `install/hardware/all.sh` |
| User-facing `omarchy-*` command | `bin/omarchy-<group>-<verb>` — see `GROUP_DESCRIPTIONS` in `bin/omarchy` |
| New theme | `themes/<name>/` (+ matching templates under `default/themed/` if they need theme colors) |
| One-shot fix for installed systems | `migrations/<unix-timestamp>.sh` (use `omarchy-dev-add-migration --no-edit`) |
