+**Gentoo (OpenRC / systemd)**
+
+Ebuild in `pkg/gentoo/app-containers/unitdore/`. Copy it into a local overlay, then:
+
+```bash
+ebuild unitdore-<ver>.ebuild manifest   # once per version
+sudo emerge app-containers/unitdore
+```
+
+**Void Linux (runit)**
+
+Template in `pkg/void/srcpkgs/unitdore/`. Copy it into a `void-packages` checkout, then:
+
+```bash
+./xbps-src pkg unitdore
+sudo xbps-install --repository=hostdir/binpkgs unitdore
+```
+
+Set `init: runit` / `init: openrc` in the config if autodetect picks the wrong one.
