+"""Test that install_required_software declares the expected base packages.
+
+inetutils provides /usr/bin/ftp, which TRAMP's /ftp: method (ange-ftp) shells
+out to; Arch ships no command-line ftp client by default. It must be in the
+base install so every machine gets it (Craig's dirvish config has an FTP
+quick-access entry that depends on it).
+
+Method mirrors test_orchestrators: sed-extract install_required_software from
+the real `archsetup`, stub pacman_install as a recorder that echoes the package
+name, run, and assert membership.
+
+Run from repo root:
+    python3 -m unittest tests.installer-steps.test_required_software
