With current partman-auto, that would be 10GB, which is the maximum
size give for / in partman-auto "home" recipe. Any desktop system
(which is often  what the "home" recipe is chosen for) fits in this.


The swap size is maximized to 3 times the system RAM, which is
apparently what you got.

I think one can read about everything...and the contrary...about the
optimal swap size.

Indeed, 3 times the memory size seems too big, particularly with large
amounts of RAM ("large" varies over time!).

Good pointers welcomed to eventually adapt this...
