KDebconf

Quick hack in the early KDE-Debian days

Fully integrated into Debconf in Debian

Some more work neededFaceliftingCode cleaning

No impact for the user he can start using it out of the box

KDebconf

Goals and AchievementsWhat is being worked on?

Pakager / Quickpackage

GUI frontend / CLI tool

Make the package processeasy

Packagers can win time forthe first packaging

Mostly for packagingapplications...... but provides a goodfoundation for morecomplex packaging

Interaction with KDevelop isplanned

Easy for regular users too,tailored packages made easy

Kapture overview

The package management system with assorted libraries

libcapture: frontend-building toolkit

libkapture: set of KDE widgets based on libcapture

The KDE frontends:KaptureKurrent

More frontends planned:CLI for command-line freaks and cron magicMore specialized single-task KDE frontends:

Single package installer partMinimalistic group-based manager

KaST: Overview

Requirements and expectations:

Reduce work for both Debian and Kalyxo/KaST developers

Do not annoy power-administratorBe cross-desktop, but avoid some of the trade-offs

Debconf as a communication and answer-caching layer

Two frontendsDebconf - familiar debconf wizardsKastconf - configlet-like custom UIs

Backend systemBridge config files to frontendsSemi-bidirectional

KaST: Backends

Generic backend library provided

Help with parsing conffilesCollection of rewrite and matching algorithmsConvenient utilities for backend writersMake backend writing reasonably easy

Parses conffile as good as it can

Rewrites (parts of) the conffileUsing the data from user

Part of respective package

Will be able to reconfigure package safelyGuard against stomping over user changesPossibly by comparing checksum with a stored one
