[$] Debian changes OpenSSH packaging

In the wake of the XZ
backdoor, the Debian project has revisited some of the
patches included in its OpenSSH
packages to improve security. The outcome of this is that the project
will be splitting out support for Kerberos key exchange into a
separate set of packages, though not until after the Debian 13
('trixie') release expected next year. The impact on Debian users
should be minimal, but it is an interesting look into the changes
Linux distributions make to upstream software as well as some of the
long-term consequences of those choices.
