Comment 3 for bug 2048876

I thought I commented on this during some past triage rotation, but apparently I didn't.

Implementing "negation" for pool or server entries is going to be tricky (I can think of many corner cases), it's going to make the config painful to read, the patch is unlikely to be trivial and unlikely to be upstreamed.

We should maybe split the server/pool configuration out of the main conf file, put it in a .d fragment _not_ handled by ucf, but rather handled by maintainer scripts or by debconf, with a preseeded, low-priority question. Or maybe there's a way to tell dpkg to always treat a specific conf file in "confold" mode.

As Sergio said, ideally these packaging changes should be implemented in Debian.
