Bob's Guide to System Upgrades With Debian

[Bob Proulx]

I promised that I would write up the way I prepare a system for doing
an upgrade.  It is the preparation that ensures that an upgrade flows
smoothly or has problems.  I have added this to the Savannah documentation.

    Bob's Guide to System Upgrades With Debian
    and Debian based systems such as Trisquel, Ubuntu, Mint

    https://savannah.gnu.org/maintenance/BobsGuideToSystemUpgrades/

In particular I describe the problem of "obsolete conffiles".  How to
check for them.  How to resolve them.
