Request: Ability to create temporary chrooted user

[lowlevl]

When your friend needs to download or upload files to your server, it will have access to your server and might create some shit in it, if per example he doesn't know Linux very well.. So if you add ability to make chrooted user, that can do anything and when logout it removes all his chrooted content (By modifying .bash_logout and setting mask to 055, so he can't modify it).

It could be great :D
