Hey. Clarifying on this:
With "clean up" I didn't mean "remove"... ;-) AFAICS, the two files are now contained in util-linux-extra (again as conffiles). On a Debian sid system of mine (that I typically upgrade every day - so it got every version in between installed),... the files are in fact *only* registered as conffiles for util-linux-extra, and don't show up as obsoletes. However, on one system that I upgraded few days ago from bullseye to bookworm I get: # dpkg -S /etc/init.d/hwclock.sh /etc/default/hwclock util-linux-extra: /etc/init.d/hwclock.sh util-linux-extra: /etc/default/hwclock => ok, still good but: # dpkg-query --showformat='${Package}\n${Conffiles}\n' --show ... util-linux /etc/pam.d/runuser b8b44b045259525e0fae9e38fdb2aeeb /etc/pam.d/runuser-l 2106ea05877e8913f34b2c77fa02be45 /etc/pam.d/su 60fbbe65c90d741bc0d380543cefe8af /etc/pam.d/su-l 756fef5687fecc0d986e5951427b0c4f /etc/init.d/hwclock.sh c06bc68c12cbdd9c7f60ba25ee587efe obsolete /etc/default/hwclock 02f94aaf57aff4e2e6751ec7b877a997 obsolete util-linux-extra /etc/default/hwclock 02f94aaf57aff4e2e6751ec7b877a997 /etc/init.d/hwclock.sh c06bc68c12cbdd9c7f60ba25ee587efe util-linux-locales ... So for some reason it's still registered to both as conffile. I always though, dpkg -S would show that, too. Cheers, Chris.
