Package: debconf Version: 1.5.77 dpkg-reconfigure debconf sets files in /var/cache/debconf whosemodes (permitions) are not as configured in /etc/debconf.conf. I guess it is also because of the umask setting.
How to reproduce? 1. Set the mode of config at /etc/debconf.conf to 0644. 2. Manually chmod /var/cache/debconf/config.dat to 0644, just to be sure. 3. Set root umsak for something restrictive, such as 0077. 4. Run dpkg-reconfigure debconf. 5. Compare /var/cache/debconf/config*.dat actual value to the mode from /etc/debconf.conf. 6. Now repeat the procedure while setting root's umask at step 3 for something less restrictive, such as 0022.
