Bug#778675: openssh-server: conf.d directory for configuration snippets (similar to nginx or apache)

[Laban Mwangi <lmwangi@gmail.com>]

Package: openssh-server
Version: 1:6.6p1-2ubuntu2
Severity: wishlist
Tags: upstream

Dear Maintainer,
 It would be nice if openssh-server had a config directory in the same vein as /etc/nginx/conf.d. 
This would allow third party packages to add config blobs without mangling /etc/ssh/sshd_config.
As an example, I would like to add support for sftp-internal iff a specific package is installed
(For sftp only access to a chrooted path). If there was a conf.d directory, the deb package could
have dropped the relevant config block and SIGHUP'd sshd. With the current setup, I'll probably be 
forced to use debian overrides to replace the existing /etc/ssh/sshd_config.
