SFTP chroot: Writable root

[Dr. Nagy Elemér Kár oly]

Dear OpenSSH Developers,

I believe that many admins would appreciate a functionality similar to the Apache HTTP Server's "DocumentRoot" in SFTP.

I am sure many admins did and will try to use chroot instead as the "close enough match, should work" solution - opening 
up multiple cans of worms.

OpenSSH does not *need* DocumentRoot. But I think it would greatly ease the work of overloaded admins and it could 
increase security by reducing the number of ill-configured SFTP servers.

I would gladly implement this functionality if somebody is willing to sponsor me in integrate it in the next portable 
OpenSSH release. I am unmotivated to move forward without a sponsor as my previous patch [1] is ready for integration for 
many weeks and I got no reply for my requests, not even a "No, stupid.".

Best wishes:
Elmar
