cupsys package silently destroys existing /etc/printcap

[Henry House]

Package: cupsys
Version: 1.2.4-2ubuntu3
Severity: serious
Justification: Policy 10.7.3 "Configuration Files: Behavior"

Installing this package silently causes an /etc/printcap to be overwritten
with an empty file, without asking the user. In my case it did not even
save a backup of the original file. Clobbering locally modified
configuration files is a violation of Debian packaging policy, section
10.7.3, which says that users' local modifications are to be preserved.
