- Arch: remove system user creation, root:root ownership, fix $startdir path in PKGBUILD
- RPM: uncomment BuildRequires, add runtime deps (openssl-libs, ca-certificates), remove system user, root:root ownership
- Alpine: remove system user creation, root:root ownership, co-locate install script with APKBUILD
- All platforms now match Debian: no system user, root:root, create dirs, copy example configs, enable service
