"""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
