Template - Root disk size changes

[Gaspare A Silvestri]

Hello everybody,

is it possibleincreasing the root disk size on a predefined template?
What I'm trying to sayisthat if I'll deploy a template with a thin disk 
starting from 10GB, for example, and I will decide to create an instance 
with 50GB HDD, is this extension automatically performed by 
CloudStack?Or have I got to create many different templates with 
different root disk sizes?

Thanks in advance,

Gaspare
