As do most of us. An upgrade won't overwrite configuration file changes whereas
with
a new install you do lose them!
Suppose version N of some software package has M configuration settings,
and version N+1 has M with additions +X and deletions -Y.
If I am running version N, have changed the configuration file to M',
and then upgrade to version N+1, you're saying dist-upgrade throws away
+X and -Y. I may want or need those.
Whereas, if I backup, wipe, install, and restore, I can diff M' and (M
+X -Y) and manually solve the three-way merge problem.
