Note that it is intended to activate these options per default in the - future, but as it drastically changes the way APT calls &dpkg; it needs a lot more testing. - These options are therefore currently experimental and should not be used in - production environments.

The "smart" way is to - configure only packages which need to be configured before another - package can be unpacked (Pre-Depends), and let the rest be configured - by &dpkg; with a call generated by the ConfigurePending option (see - below). On the other hand, "no" will not configure - anything, and totally relies on &dpkg; for configuration (which at the - moment will fail if a Pre-Depends is encountered). Setting this option - to any value other than all will implicitly also - activate the next option by default, as otherwise the system could end - in an unconfigured and potentially unbootable state. - - - If this option is set APT will call dpkg --configure --pending - to let &dpkg; handle all required configurations and triggers. This option is activated automatically - per default if the previous option is not set to all, but deactivating it could be useful - if you want to run APT multiple times in a row - e.g. in an installer. In these sceneries you could - deactivate this option in all but the last run. - - - Useful for the smart configuration as a package which has pending - triggers is not considered as installed, and &dpkg; treats them as unpacked - currently which is a showstopper for Pre-Dependencies (see debbugs #526774). Note that this will - process all triggers, not only the triggers needed to configure this package. - - - Essential packages (and their dependencies) should be configured immediately - after unpacking. It is a good idea to do this quite early in the upgrade process as these - configure calls also currently require DPkg::TriggersPending which - will run quite a few triggers (which may not be needed).
