Bug#402497: openssh-server: Upgrade from Sarge erases host keypairs

[Rémi Denis-Courmont <rdenis@simphalempin.com>]

Package: openssh-server
Version: 1:4.3p2-6
Severity: grave
Justification: causes non-serious data loss

	Hello,

Replacing Sarge "ssh" package with Etch "openssh-server" and
"openssh-client" package causes the host keypairs to be unduely
regenerated, and the old keys are permanently erased and lost.
This is very annoying for SSH users.
