This question already has an answer here:
As far as I know, Steam (and pretty much every other application) is installed to the "/" partition. If that's the case, why is such a small "/" partition recommended? Couldn't one or two Steam games wipe out your "/" fairly easily? It seems like a "/" partition of 20GB max is usually recommended.
Am I missing something, or if I plan on installing games and applications should I make a larger "/" partition?
EDIT: I'm asking because I haven't actually seen anyone mention this before. The general recommendation is to have a seperate /boot, /, /home, and swap partition, and the general consensus is that a "/" partition doesn't need to be any bigger than 10GB - 20GB. It seems as though everyone recommends something like this:
/boot - 500MB
/ - 10GB - 20GB
swap - same as RAM
/home - rest.
Maybe I'm weird, but looking at my Windows 7 install "Program Files accounts for nearly 700GB of disk usage, and everything else (including Windows 7) is barely 100GB. Is that not normal? It just seems more normal in my mind to have "/" and /home switched.
