Privilege separation across all installers so the long-running services no longer run with full administrative rights:
betterdesk.sh: installer keeps root but systemd units now run as a dedicated unprivileged 'betterdesk' system account by default (auto-created via ensure_service_user). Added full systemd hardening for the Go server (NoNewPrivileges, ProtectSystem=strict, ProtectHome, PrivateTmp, ReadWritePaths) and light hardening for the Node.js console. chown migrates existing root-owned data to the service account on update. Opt-out via --run-as-root / BETTERDESK_RUN_AS_ROOT=1; custom account via BETTERDESK_SERVICE_USER. Minimal mode covered too.
betterdesk.ps1: NSSM services now run under their per-service low-privilege virtual accounts (NT SERVICE\<service>) instead of LocalSystem, with scoped icacls grants on the install/data dirs (Set-ServiceLeastPrivilege helper). Applied to the Go server, Node.js console and minimal-mode service. Opt-out via -RunAsRoot / BETTERDESK_RUN_AS_ROOT=1.
Docker: verified already privilege-separated (supervisord drops both programs to user=betterdesk; multi-container images drop via su-exec).
Also bundles in-progress changes to the Go server API, Node.js console services and Docker compose/Dockerfiles.
This commit was made possible thanks to Insolve.
- deployServerBinary: use rename(2) for atomic replace, fixes ETXTBSY
when target Go binary is busy (Linux kernel handles inode swap).
Falls back to copyFileSync on cross-device rename or non-Linux.
Windows: rename target out of the way first, then move new in.
- settings.js: mark 'server' phase as error when build succeeded but
deploy failed (was incorrectly marking 'done' from build alone).
- settings.js: completion modal now shows error title, error message
and pre-formatted stderr when serverDeploy.success === false.
- i18n: added complete_with_errors, modal_done_with_errors_title in
en/pl.
