Package: dpkg
Version: 1.20.9
Severity: wishlist
Packages that have a plugin architecture, like glib2.0 and gdk-pixbuf,
often want to know the multiarch tuple in their maintainer scripts so
that they can enumerate plugins in a multiarch-qualified directory or
run multiarch-qualified helper programs.
At the moment, dpkg provides DPKG_MAINTSCRIPT_PACKAGE and
DPKG_MAINTSCRIPT_ARCH in maintainer scripts' enviroment, but packages
that need to know the multiarch tuple have to generate their maintainer
scripts from a template: for example, glib2.0 and gdk-pixbuf have a
.postinst.in template containing #MULTIARCH#, which gets substituted by
the package build.
It would be simpler for packages in this situation if dpkg provided
something like DPKG_MAINTSCRIPT_MULTIARCH in the environment.
