Automated VM with Synology DSM – Proxmox

I was looking into install Synology DSM on Proxmox and find out there are several Loaders to make it possible to boot DSM on non Synology hardware. Looking further I found a blog with a script to instal “Arpl loader” and DSM on Proxmox, the problem is that “Arpl loader” now is old and not maintained, also you cannot use the last version of Synology DSM with this old boot loader, so I modified the script for an Automated Install on Proxmox of Synology DSM creating a VM ready to boot.
