Just: /etc/init.d/pcscd Not sure where dpkg keeps actually track of it's (obsolete) conffiles, I think it's in: /var/lib/dpkg/status: /etc/reader.conf.d/0comments 5ca480422c33bfe1fdcf7299289a12c9 obsolete > The "remove-on-upgrade" flag as documented in remove-on-upgrade(5) > may be a better option. Probably. Maybe this simply creates a dpkg-maintscript-helper line in the maintainer scripts. > My problem is that the file has been removed from the pcscd package > 10 years ago. > So it will be time consuming (on my side) to check the fix is > working.

Hmm I don't think this is really necessary... or do you see any big dangers in "blindly" removing an obsolete conffile, that was anyway just a README file? > Can't you just erase the file from your system? Well I for my self have already cleaned it up manually... but how many tens of thousands Debian installations are out there which will have such legacy cruft lingering around forever? Therefore I think it's always good practise to properly clean that up for the benefit of everyone. Cheers, Chris.
