Bug#241496: openssh-server: Still seen 5 years later

[Phil Carmody <pc+debian@asdf.org>]

Package: openssh-server
Version: 1:5.5p1-6
Severity: serious


I performed the upgrade to 1:5.5p1-6 months ago, I don't know what
version I was coming from. All I know is that my customised
sshd_config was overwritten during the upgrade. As this 'upgrade'
resulted in the opening of world-facing ports against my will, I 
consider it to not just be a grave error as it's not just a loss 
of data, but also a security issue.

It's clearly at least serious, as it violates 10.7.3's
    * local changes must be preserved during a package upgrade
	  
Chatting with a debian dev, the idea of this possibly being a 
dpkg bug was mentioned. Has that possibility been looked into at
all?
