I've installed ArchLinux yesterday and set up a 10 GB partition for the root file system, 256 MB for swap, and the rest (456 GB) for my /home.
However I still have 4.0 GB left on my root file system after installing some packages (GNOME, Firefox, Thunderbird etc...) and running a pacman clear cache.
Does it suffice to have 10 GB for root file system, or could I end up running out of space in a couple of weeks/months?
