I am upgrading several systems from etch to lenny, and ideally I
should be able to preseed every question. The main problem I'm having
is with UCF questions (ie should this configuration file be
overwritten by the package maintainer's version?).
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
and
> 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
