+# as root, repository mounted read-only at /work, SU_DISTRO=<label>):
+#   1. installs the applet as /usr/local/bin/skeptical-updater
+#   2. builds the deterministic fixture for the package-manager family (su-dummy-{a,b,c}
+#      1.0 installed, 2.0 offered by a local repo; the distro's own repos are disabled;
+#      su-dummy-orphan: an unrelated, automatically installed package nothing needs)
+#   3. runs tests/e2e/*.bats with the vendored bats-core against the REAL package manager
+# Exit status: the bats status (or 1 if the setup failed).
