Confirmed live: install_frigate()'s fresh-install path overwrote a
working, hand-crafted docker-compose.yml (Frigate + mosquitto +
frigate-notify) with zero backup, because that file's shape didn't match
what frigate.sh's own "existing install" detection knew how to recognize.
Every service's own detection is a judgment call about what counts as
"already installed" and can miss a real setup built outside this repo's
conventions.
lib/common.sh gains backup_if_exists(FILE) — copies FILE to
FILE.bak.<timestamp> if it exists, no-ops otherwise (including DRY_RUN).
Applied before every service's own `cat > docker-compose.yml`/`cat > .env`
write across all 60 services that do one (115 call sites), plus a matching
standalone-mode stub added to every service's own bootstrap block, same
convention already used for port_in_use/find_free_port. This doesn't
replace a service's own update/fresh-reinstall detection — it's the safety
net underneath it, so a wrong detection costs a .bak file to restore from
instead of the original silently disappearing.
Also fixes the actual gap that surfaced this: services/frigate.sh's
Authelia offer only checked for Authelia installed locally on Frigate's
own box, which is never true for a dedicated NVR box with no local Caddy
either (the common shape — Caddy lives elsewhere, snippet-generation mode
already handles that). Now offers Authelia protection unconditionally and,
when Authelia isn't local, asks whether it lives on the same machine as
Caddy (still "import authelia", since that's local to wherever Caddy ends
up) or on a genuinely separate third machine (the explicit
header-pinned forward_auth form, per CLAUDE.md's "forward_auth to a remote
Authelia" note, needed because a bare authelia:9091 shortcut only works
one hop).
Same bug class just fixed in mattermost.sh: immich, joplin, koha,
mail-archiver, and nextcloud all generated a fresh random
DB/admin password on every single run with no check for an
existing one. Each backs its database with a persistent volume, so
Postgres/MariaDB keeps the password from its first init while the
freshly overwritten .env (or config-main.env for koha) no longer
matches it — any rerun would have locked the app out of its own
database. koha, mail-archiver, and nextcloud also regenerated an
app-level admin login password the same way.
Found by cross-referencing every service with a DB password against
which ones actually guard reuse on rerun (only traccar.sh did,
already correctly) rather than waiting to be told about each one
individually.
Fix mirrors traccar.sh's existing pattern: read the password back out
of the existing .env/config file if present, only generate fresh when
there's genuinely nothing there yet.

traccar.sh's caddy_net wiring was fixed to mirror configure_caddy_for_service's
own mode resolution (CADDY_MODE from site config, then a local ~/docker/caddy,
then the legacy CADDY_REMOTE_HOST var) instead of only checking for the local
directory. That same bare directory check was copy-pasted into the caddy_net
wiring of every other Docker service in the repo, so a site with Caddy on a
different box would silently fail to join any of their containers to caddy_net
during setup (or, for homeassistant/koha, only get half the wiring right).
Applied the same fix mechanically across all 37 services using the standard
_CADDY_NET_BLOCK/_CADDY_NET_SECTION pattern (verified identical text via
scripted diff before touching any of them), plus by hand for:
- homeassistant.sh and koha.sh, which use their own differently-shaped
variables (HA_CADDY_NET_LINES / _CADDY_NET_ENTRY) for the same decision
- paintplus.sh and ai-stack.sh, which do a live `docker network connect`
instead of a compose network block
- watchyourlan.sh, whose Caddy note was worded for local-only setups
sms-inbound.sh got more than a mode swap: its Caddy wiring was hand-rolled
(not routed through configure_caddy_for_service) and had no remote-Caddy
path at all — a remote Caddy box would get a misleading "Caddy isn't
installed here" message instead of a snippet. Added
_sms_write_caddy_snippet(), mirroring the snippet-file pattern
configure_caddy_for_service uses everywhere else, and pointed the firewall
gate at the same three-way mode instead of a two-way dir check.
Verified: bash -n across all of services/*.sh, a scripted check that every
touched file has exactly one _CADDY_MODE resolution and no leftover bare
`[ -d "$DOCKER_DIR/caddy" ]` feeding a caddy_net decision, and spot-checked
docker compose config renders (traccar, mattermost) confirming the ${VAR}
interpolation and multi-service usage sites still resolve correctly.
New site config key: CADDY_REMOTE_HOST (set via 'sudo ./setup.sh configure').
When set, configure_caddy_for_service operates in "remote" mode instead of
writing to a local Caddyfile:
- Upstream uses CADDY_REMOTE_HOST:PORT (host IP, not container name)
- Snippet saved to ~/docker/caddy-snippets/<subdomain>.caddy
- User is shown scp/rsync commands to copy it to the Caddy machine
Three modes in configure_caddy_for_service (lib/common.sh and inline stubs):
local: ~/docker/caddy/ exists → write Caddyfile + reload (existing behavior)
remote: CADDY_REMOTE_HOST set → save snippet, print copy instructions
none: neither configured → silent return (unchanged)
All 31 service standalone bootstrap stubs updated with the new logic.
CADDY_REMOTE_HOST global added to all 42 standalone bootstrap sections.
setup.sh configure now prompts for CADDY_REMOTE_HOST with a clear explanation.
wolf.sh: add missing stubs (configure_caddy_for_service, write_readme,
prompt_yn, ensure_docker_dir_ownership) and the Authelia/Caddy/start calls
that were missing from the install function.

Each service can now be run directly with sudo bash <service>.sh on any
machine with Docker installed, without needing the full post-install repo.
Uses the shared bootstrap pattern from docs/standalone-template.sh.
