DYODE 1.4.0

Added

• File-share setup. After the setup wizard, install.sh asks whether to
  share a DYODE folder over NFS and/or SMB, on either box: received files on
  the output box (read-only by default), a drop folder on the input box
  (read-write). Unattended: --share-nfs PATH=CLIENTS[:rw],
  --share-smb PATH=USER[:rw], --smb-password-file, and --shares-only to
  change shares on an installed box without reinstalling.
• Shares live in one managed block in /etc/exports and
  /etc/samba/smb.conf; everything outside it is untouched. Re-running the
  same command changes nothing, so it suits Ansible. smb.conf is checked
  with testparm before it is installed, a rejected export is rolled back,
  and every file changed keeps a backup.
• Refused before anything is written: sharing DYODE's staging folder or a
  folder containing it, NFS to everyone, SMB guest access, SMB as root, and
  paths or names that could inject settings into either file.
• Clients for the file-sharing services. --with ssh-client,
  nfs-client and smb-client (or clients for all three) install only
  the client: sftp/scp/ssh, mount -t nfs, and mount -t cifs plus
  smbclient. For a box that connects out and should run no server.
• smbclient is now bundled, and --with smb installs it alongside Samba;
  --with ssh now names openssh-client explicitly. Each server therefore
  comes with its client, so its shares can be tested as localhost.
