Hi Christoph, and thanks for your bugreport,

That's really weird; cups.maintscripts has the following lines:

rm_conffile /etc/cups/acroread.conf 1.4.4-2~
rm_conffile /etc/cups/pdftops.conf  1.4.4-2~

That lead to these in the maintainer scripts:

dpkg-maintscript-helper rm_conffile /etc/cups/acroread.conf 1.4.4-2~ -- "$@"
dpkg-maintscript-helper rm_conffile /etc/cups/pdftops.conf 1.4.4-2~ -- "$@"

I could bump that version to 1.6.2-9~ to make sure they are cleaned in the 
Jessie upgrade, according to dpkg-maintscript-helper manpage:

That's kinda-expected, the directory (and it's contents) is now shipped by 
cups-daemon instead, I think the warning is harmless (and actually a sign of 
an intended action across upgrades).

Same situation here, these files changed owner from cups to cups-daemon. And 
rm -rf'ing under the feet of cups{,-daemon} is a bad idea I think.

Opinions ?
