Installing Debian remotely in an unmanaged VPS

[Mario Castelán Castro <marioxcc.MT@yandex.com>]

Hello.

I'd like to install Debian in an unmanaged VPS which has Debian 
installed already. This is so that I can customize the installation by 
using LVM for instance. I'm following 
<https://wiki.debian.org/DebianInstaller/Remote> but it seems like I'd 
have to keep an ISO image in the hard disk and would need to keep at 
least one partition intact. Is there a way to avoid this?. I.e: a way so 
that I can completely reformat the hard disk?.

I found <http://www.centosx.com/install-centos-remotely-through-vnc/> 
for CentOS. Apparently there are images expressly configured for this 
task. Is there something similar for Debian?.

Regards and thanks.
