librelad c11052b753 fix(mastodon): make tag annotations substitutable
The tag manager reads `#LIBREPORTAL|<TAG>|<VALUE>` and takes <VALUE> as the
current literal to search for on that line, so it must equal the string in the
line body. Mastodon used `unconfigured` as the annotation value against bodies
like `PASSWORD_TAG_1_DATA` — nothing matched, nothing was ever substituted, and
the placeholder shipped as the live database password, SECRET_KEY_BASE, OTP
secret and VAPID keypair.

Nothing caught it either: `unconfigured` doesn't match `_DATA`, so
tagsManagerGetTagState reported the tags as configured, and the stale-tag gate
in dockerComposeUp (which tests the annotation value against
`^[A-Z][A-Z0-9_]*_DATA(_[0-9]+)?$`) let the app start.

Adopt the convention every other app already uses — body placeholder identical
to the annotation value, `<KIND>_DATA_<n>`. All 11 tags now substitute, the app
and postgres services agree on the same generated credentials, and an unfilled
tag is visible to the pre-start gate.

Existing 0.1.0 installs keep their literal credentials until re-installed, and
their Postgres was initialised with them, so a plain re-install desynchronises
the compose from the volume. Document both recovery paths in upgrade notes.

# LibrePortal — Install & Use
How to install, place, update, and remove LibrePortal. For building releases or
running a dev copy, see [development guide](../contributing/development.md).
> **Note:** the `get.libreportal.org` host isn't live yet. Until it is, install
> from a local release artifact or a git/local checkout — see
> [development guide](../contributing/development.md). The commands below are the intended public flow.
## Requirements
- A **Debian** or **Ubuntu** host.
- **root** (run with `sudo`).
- `curl` (or `wget`) and `tar`.
## Install
```bash
curl -fsSL https://get.libreportal.org/install.sh | sudo bash
```
This downloads a versioned, **checksum-verified** release tarball (no git, no
login), installs LibrePortal, and prints the WebUI address + a generated password
(also saved to the install log). To choose the password yourself add
`--password=…`.
### Put data where you want it (separate disks, external drives)
LibrePortal uses **three independent roots**, each can be its own path/disk:
| Flag (default) | Holds | Owner |
|---|---|---|
| `--system-dir=/libreportal-system` | configs, database, logs, install | the manager user |
| `--containers-dir=/libreportal-containers` | live app data | the container user |
| `--backups-dir=/libreportal-backups` | backup repositories | the container user |
```bash
curl -fsSL https://get.libreportal.org/install.sh | sudo bash -s -- \
--system-dir=/mnt/ssd/libreportal \
--containers-dir=/mnt/ssd/libreportal-apps \
--backups-dir=/mnt/bigdisk/libreportal-backups
```
Notes:
- Defaults are top-level dirs on purpose — they avoid the permission/encryption
pitfalls of living inside a user's home. To put `containers`/`backups` inside
`/home/<user>` you must add `--allow-home` (it needs the container user to
traverse that home — a small privacy trade-off).
- Other flags: `--manager-user=NAME` (default `libreportal`),
`--channel=stable|edge` (default `stable`), `--version=X.Y.Z` (pin a version).
## Where things end up
```
<system-dir>/ configs/ logs/ install/ database.db ssl/ ssh/
<containers-dir>/ one folder per installed app (+ the libreportal WebUI)
<backups-dir>/ one folder per backup location
```
The locations are chosen at install and fixed afterward (changing them is a
deliberate reinstall, not a setting — this is part of the security model).
## Update
LibrePortal checks its channel for a newer version and shows a badge in the WebUI
when one is available. Apply it from the dashboard, or on the host:
```bash
libreportal update apply # update now if a newer version exists
libreportal update check # just re-check the channel
```
Updates download + verify the new release tarball and redeploy. Your data,
configs, and backups are untouched (they live outside the replaced install tree).
Some releases carry a fix that an already-installed app only picks up on its next
install — see [upgrade notes](upgrade-notes.md) for the versions that need a
manual step.
## Backups on an external / removable drive
Point a backup location at the drive's mount path. For a removable disk, set
**Require Mounted Drive** on the location (config key
`CFG_BACKUP_LOC_<n>_REQUIRE_MOUNT=true`): LibrePortal then **refuses to back up
when the drive isn't mounted**, so an unplugged disk never silently fills your
system disk. Use a Linux filesystem (ext4/xfs/btrfs) — FAT/exFAT/NTFS can't hold
the required ownership and will warn.
## Uninstall
```bash
sudo libreportal-uninstall
# keep the rootless Docker layer + image cache for a fast reinstall:
sudo libreportal-uninstall --skip-docker-images
```
`libreportal-uninstall` is a fixed command on `$PATH` (no data path to type — it
reads the real install locations from the installed service, so it works even with
custom roots). It removes the three roots, the system users, and the small
out-of-tree footprint (`/usr/local/lib/libreportal`, the `/etc` integration files).
> ⚠️ Uninstall permanently deletes all app data, configs, and the database. Take a
> backup first if you want to keep anything.
