I don't know if this is doable, but I can conceive it.

So, here is what I want to do:

1. Make user on box 1 but have /home/user on server (box 2)
2. Box 1 connects to (box 2) via the Internet
3. Box 1 connects to box 2 via ssh
4. Box 2 is an ssh server

So far, this is what I have done

1. Allow passwordless login between box 1 and box 2
2. create /home/user mock on box 2
3. edit /etc/fstab on box 1 so that it attempts to mount the remote ssh folder (/home/local/BSB/cyberman/homefolderlaptop/cyberman) to /home/cyberman (local directory) on box 1
4. Tried to mount it

Supposedly, I'm getting some junk..

Yeah, well, of course it's not empty.
I don't see how I can have the remote folder mounted yet create a user in it?

I've tried removing the /home/cyberman on the local. And then I mounted the remote folder and attempted on the local machine to make the user. The add new user gui feature in Debian will not allow me to make the user this way, as the folder already exists.

Can you mount the remote folder in a subdirectory like /home/cyberman/remote
solution
mount a remote home folder create a new user will be created on the remote server and copy required content to the folder. If you want the remote user and the user on the server to have the same folder they must have the same user id.
