The tutorial says "Add sid to your sources.list".  So, I added the 
following lines to /etc/apt/sources.list:

    deb     http://ftp.us.debian.org/debian/ sid main
    deb-src http://ftp.us.debian.org/debian/ sid main


Today, having completely forgotten about the backport, I ran 'apt-get 
update' and 'apt-get upgrade'.


'apt-get update' produced more output that usual.


'apt-get upgrade' wanted to download and install 800+ packages.  When I 
approved, it failed:

        <snip>
        Errors were encountered while processing:
         /tmp/apt-dpkg-install-ke7tUq/128-cryptsetup_2%3a2.2.2-2_amd64.deb
        E: Sub-process /usr/bin/dpkg returned an error code (1)


So, I ran 'apt-get upgrade' again -- fewer packages, but same result:

        <snip>

Then I remember the backport.


Rather than troubleshoot this mess, I re-imaged the drive to an image 
taken prior to build the backport.  'apt-get update' and 'apt-get 
upgrade' then worked as expected.


So, beware of adding things to your /etc/apt/sources.list -- you may be 
in for unwelcome surprises the next time you update/ upgrade.


And, take images of your system drives regularly.
