+ dpkg trigger usage (and related options)

+ install / upgrade. Note that it is intended to activate these options per default in the

+ not cause (big) trouble in the future. If you have understand the current risks and problems with
+ these options, but are brave enough to help testing them create a new configuration file and test a
+ combination of options. Please report any bugs, problems and improvements you encounter and make sure

+
+ DPkg::NoTriggers
+ Add the no triggers flag to all dpkg calls (expect the ConfigurePending call).
+ See &dpkg; if you are interested in what this actually means. In short: dpkg will not run the
+ triggers then this flag is present unless it is explicit called to do so in an extra call.
+ Note that this option exists (undocumented) also in older apt versions with a slightly different
+ meaning: Previously these option only append --no-triggers to the configure calls to dpkg -
+ now apt will add these flag also to the unpack and remove calls.
+
+ PackageManager::Configure
+ Valid values are "all", "smart" and "no".
+ "all" is the default value and causes APT to configure all packages explicit.
+ The "smart" way is it to configure only packages which need to be configured before
+ another package can be unpacked (Pre-Depends) and let the rest configure by dpkg with a call generated
+ by the next option. "no" on the other hand will not configure anything and totally
+ relay on dpkg for configuration (which will at the moment fail if a Pre-Depends is encountered).
+ Setting this option to another than the all value will implicit activate also the next option per
+ default as otherwise the system could end in an unconfigured status which could be unbootable!
+
+
+ DPkg::ConfigurePending
+ If this option is set apt will call dpkg --configure --pending
+ to let dpkg handle all required configurations and triggers. This option is activated automatic
+ per default if the previous option is not set to all, but deactivating could be useful
+ if you want to run APT multiple times in a row - e.g. in an installer. In this sceneries you could
+ deactivate this option in all but the last run.
+
+ DPkg::TriggersPending
+ Useful for smart configuration as a package which has pending
+ triggers is not considered as installed and dpkg treats them as unpacked
+ currently which is a dealbreaker for Pre-Dependencies (see debbugs #526774). Note that this will
+ process all triggers, not only the triggers needed to configure this package.
+
+ PackageManager::UnpackAll
+ As the configuration can be deferred to be done at the end by dpkg it can be
+ tried to order the unpack series only by critical needs, e.g. by Pre-Depends. Default is true
+ and therefore the "old" method of ordering in various steps by everything. While both method
+ were present in earlier APT versions the OrderCritical method was unused, so
+ this method is very experimental and needs further improvements before becoming really useful.
+
+
+ OrderList::Score::Immediate
+ Essential packages (and there dependencies) should be configured immediately
+ after unpacking. It will be a good idea to do this quite early in the upgrade process as these
+ these configure calls require currently also DPkg::TriggersPending which
+ will run quite a few triggers (which maybe not needed). Essentials get per default a high score
+ but the immediate flag is relatively low (a package which has a Pre-Depends is higher rated).
+ These option and the others in the same group can be used to change the scoring. The following
