Small side note: in your case (single Arch: any package) I don't think it's necessary to split -arch and -indep override targets (I only do that in dietlibc because it also builds a Arch: all -doc package where I don't want to run the full build), and you could just use a simple override_dh_auto_install: and override_dh_auto_clean:. Doesn't really hurt either, but makes debian/rules more complicated than necessary in your case. > NB: I was a bit confused that dh-exec was not called for maintscript. What do you mean? Whenever I use dh-exec it's either a) for renaming files in debian/*.install or b) for having substvars available in debian/*.install. Ah, now I see, you thought that it might be able to replace substvars in postinst... I don't believe that'll work, since postinst isn't a regular debhelper conffile, but instead always has a shebang - so debhelper will never try to execute it - in contrast to things like debian/*.install, which by default are not executable, so debhelper can distinguish between the "simple file" and "script that produces the actual contents of that file" - it couldn't do that for things that are supposed to be scripts.
