There are some ucf questions in /var/cache/debconf/config.dat:
Name: ucf/changeprompt Template: ucf/changeprompt Value: keep_current Owners: ucf Variables: BASENAME = sensors.conf FILE = /etc/sensors.conf
Name: ucf/changeprompt Template: ucf/changeprompt Value: install_new Owners: ucf Flags: seen Variables: BASENAME = apticron.conf FILE = /etc/apticron/apticron.conf
But I don't know if it's possible to preseed these at all, let alone to preseed them in a way that debconf-set-selections will grok.
Any help is greatly appreciated.As a follow-up, the other questions I've been unable to avoid prompts for is when applications ask which services to restart in order to reload an updated library. These actually have preseed values, but the installers seem to ignore the debconf preseed database. Here are examples of my preseeded values which are I pull in with debconf-set- selections before they are ignored:
libpam0g libpam0g/restart-services string cron libssl0.9.8 libssl0.9.8/restart-services string ntp exim4 ssh
