Add Arch Linux container support and integrate pacman into install utilities. New files: ct/archlinux.sh (container build/update script), install/archlinux-install.sh (install entrypoint), and json/archlinux.json (metadata). misc/install.func: detect_arch in detect_os, add pacman bootstrap, and implement pacman handlers for pkg_upgrade, pkg_install, pkg_remove, pkg_clean and package refresh; include openssh install path for pacman and provide a cleanup_lxc override to run pkg_clean. Enables creating/updating Arch Linux LXC containers and proper package manager handling.
Bump Fedora template to 43 and enhance container installation tooling. Persist DIAGNOSTICS setting and introduce post_progress_to_api() to send lightweight telemetry pings from inside containers (fire-and-forget, enabled when DIAGNOSTICS=yes and RANDOM_UUID set). Harden package management flows: re-detect PKG_MANAGER when commands are missing, add apt mirror fallback logic (apt_update_safe) and more robust apt-cacher proxy parsing. Fix Debian 13 LXC root ownership bug (chown /) and add additional DNS/Git host checks (including api.github.com). Improve downloading and validation of tools.func, add multiple post_progress_to_api hooks to signal progress, and add two new install entrypoints (misc/main/install.func and misc/main/alpine-install.func) that consolidate network checks, OS updates, MOTD/SSH setup and container customization.
Seed a default admin account and harden the installer; update symlink behavior and LXC hook argument handling.
- Install: downgrade Node setup to 22, write ADMIN_EMAIL/ADMIN_PASSWORD into /opt/trek/server/.env for initial boot, chmod the file, wait for app health, then remove plaintext creds from the env and print the default admin credentials. Remove previous DB patching script and credentials file generation. Add health-check failure handling.
- ct/trek.sh: check for /opt/trek instead of ~/.trek, run npm ci without --production, and recreate server data/uploads by removing any existing dirs and creating explicit symlinks.
- Installer: mirror symlink strategy used in the container (rm then ln -s) and ensure generated ENCRYPTION_KEY note; add ADMIN_EMAIL default.
- json: set default username to admin@trek.local, update notes about seeded admin, ENCRYPTION_KEY storage, and APP_URL recommendation.
- tools/pve/lxc-prehook.sh: fix append_unique_line_in_ct to pass positional arguments into the bash -c snippet safely (avoid parent-shell expansion).
These changes ensure a reproducible default admin creation flow without leaving plaintext credentials, improve symlink handling, and fix a bug in the LXC prehook.
