Subject: [PATCH] Properly avoid pulling unwanted packages from unstable repo

  Currently apt pulls all packages from the unstable repo because the
  script intendation created the file 'limit-unstable' with tabs in it.
  Fixed using printf to create a multiline file (which is the way
  wireguard.com/install suggests).
