My understanding is that it began when Debian began.  Individual
"official" Debian packages have never been signed.  If you have
an official Woody install CD and it's installed and running
debsigs by default, something screwy is going on.  That didn't
occur for me when I installed Woody from CD, for instance.

The default install tool for Debian does not need reconfiguration
in order to complete the initial installation.  The "debsigs"
package does, but that's not part of the standard install toolset.
I don't know why you're encountering it during a Woody install.

The way this is done with Debian is that, rather than signing the
individual packages, the individual packages are md5sumed, with the
md5sums placed in the "Packages" file that apt-get fetches during
"apt-get update" or located upon the official CDs.  Those "Packages"
files *are* signed, so that it's effectively not possible for an
evildoer to modify the md5sums stored therein.
