Critical install/update/uninstall hotfixes from the hardening plan
(docs/plans/INSTALLER_UPDATER_UNINSTALLER_HARDENING_PLAN.md §4):
- Firewall automation (G1): new sourceable scripts/lib/firewall.sh detects
firewalld/ufw/nftables/iptables and opens 80/443; install.sh runs
configure_firewall, update.sh re-ensures it idempotently. Exactly what we
open is recorded in /etc/serverkit/install-state.json (scripts/lib/state.sh)
so uninstall undoes only our rules. Fixes the #1 "installed but unreachable"
failure on fresh RHEL-family boxes.
- Accept Python 3.11 OR 3.12 (G2): locate_python now iterates
python3.12/3.11/3 and provision_python installs the distro package
(python3.11 on Debian 12, 3.12 on Ubuntu/Fedora, 3.11/3.12 on RHEL) before
ever falling back to a source compile.
- Use $PYTHON_BIN for secret generation instead of a bare python3.
- Distro-first Node 20 (replacing unconditional NodeSource): install the
distro nodejs+npm, fall back to NodeSource only when it's missing or < 18,
and validate node>=18 before continuing.
- Unify uninstall (G4): new scripts/lib/uninstall.sh is the single canonical
teardown routine shared by uninstall.sh and `serverkit uninstall` (they had
drifted — one ran `down -v`, one didn't). Default preserves user data
(volumes kept, DB snapshotted to backups); --purge/--delete-volumes removes
volumes+DB+data dirs; --keep-data preserves /etc + /var/lib + backups;
--yes/--dry-run added; honors SERVERKIT_DIR. Removes the apt lock-wait
drop-in on uninstall.
Tests: new scripts/test/test_install.sh (11 cases, source-able install.sh)
covers python/node detection, firewall dry-run + state, and the uninstall
data-handling matrix. Existing test_update.sh still green. shellcheck clean
(error + warning) on all new/changed shell.
