[RFC] Trigger directives that do not put packages in triggers-awaited
Hi,
please find attached a patch that implements 2 new directives
"interest-noawait" and "activate-noawait" for the triggers control file.
They work exactly like "interest" and "activate" but the package
that activate the triggers are not put in triggers-awaited status instead
they are directly configured. Up to now, this was only possible if you
manually activated triggers with dpkg-trigger. With this patch, the
package implementing the trigger can also specify that the trigger
is not important enough to consider that the triggering package is
not configured.
My goal is to simplify the configuration process because most
triggers are purely convenience triggers and are not required by
the triggering packages... (see man-db, bash-completion, etc.)
This will also make it more likely that the trigger is really only
executed once at the end instead of multiple times because some
package had to be configured earlier.
My main problem is how to introduce this new feature. For now, I
have added "-noawait" variants but given they are the most common case, I
wonder if I shall not change the current directive to not
put the packages in triggers-awaited and instead to add new directives
"interest-await" and "activate-await" (or "interest-crucial",
"activate-crucial") with the current behaviour. That would also reduce the
number of packages to modify to get the expected benefits... very few
packages really need to put the triggering package in triggers-awaited.
What do you think?
Also any code review is welcome of course.
Cheers,

dpkg: implement "interest-noawait" and "activate-noawait" trigger commands
Those variants do not put triggering packages in triggers-awaited status
and thus do not record the package with the corresponding pending triggers
in the Triggers-Awaited field.
This should be used for triggers which do not provide essential
functionality when we can safely consider that the triggering packages
are able to satisfy dependencies even if the trigger processing
has not yet happened.
