  def caveats; <<~EOS
    To use chroot, vsftpd requires root privileges, so you will need to run
    `sudo vsftpd`.
    You should be certain that you trust any software you grant root privileges.

    The vsftpd.conf file must be owned by root or vsftpd will refuse to start:
      sudo chown root #{HOMEBREW_PREFIX}/etc/vsftpd.conf
