reassign 330874 dpkg thanks A short summary:
During one day, in version 4.0.12-3, the login package did not include /etc/pam.d/su because of a bug in the package build process. The file was there in 4.0.12-2, was removed in -3 and was re-added in -4. This file came back very quickly in the package, but it seems that users who did the two upgrades (-2 --> -3, then -3 --> -4) were then prompted about replacing "their" /etc/pam.d/su file (which was just kept from the -2 version). Frank Küster, the bug submitter, thinks this is a bug in dpkg. However I'm not sure he's right because that means that dpkg should have kept the md5sum of the N-2 version while upgrading the N-1 to N version. I think this is impossible, but I leave to you, Scott, the final word on it. --
