RE: How about "grooming" outdated packages?
I've investigated some packages to check a bit, patched to it and rebuilt package. However, lintian prevent me to generate it since it has lintian error.
E: xxxx: maintainer-script-should-not-use-adduser-system-without-home postinst:23 'adduser --system --quiet --ingroup xxxx --no-create-home xxxx'
Well, it is popular package, maintainer is well experienced, however it _still_ has such error :-(
I wonder if some people do grooming for such packages... like security inspection.
