Is there any method, with ChrootDirectory and internal-sftp, to automatically cd to a subdir on login?

[Whit Blauvelt]

Peter,

Thanks, but as I understand it that's not an applicable answer in my
circumstance. I need each user to have a unique root directory rather than
have users share one.

If the ChrootDirectory were /home and the users were /home/user1 and
/home/user2 what you suggest would work. But in my case the ChrootDirectory
is %h and the place the users need to end up is %h/files. 

This is trivial to do with scponly. Just set the home directory in
/etc/passwd to be /home/user1//files so the chroot is /home/user1 and the cd
is to /home/user1/files. What I'd like is that same functionality using
OpenSSH's internal sftp server.

I need to chroot my users separately rather than to a common chroot because
the users and their files need to be totally invisible to each other, no
matter what.

Best,
Whit
