I usually reinstall software when I upgrade it.

I very rarely reinstall software because it is misconfigured, although later this week I have to figure out where CPAN perl lives, and downgrade one of our boxes from "CPAN" to "sarge" versions of key Perl code - hohum. Blimin mod_perl 1.999.21 to 1.999.22 upgrade.... Steve was right about packaging perl, but making packages of it all that is needed will take a long time, even with the tools available.

As discussed, you can make "apt" always purge.

Just don't expect smooth upgrades of operational systems. If a simple upgrade works, all is fine, if it fails and you need to then purge, and reinstall, all is fine, if you start by purging the customisation and then reinstall, and it doesn't work.... back to backups you go.

Whoever put "diff" for config files in the dpkg tools earns my undying thanks.
