I'm planning a clean install of my MacBook Pro with OS X 10.6 and I want to make a partition (among others) only for the sleepimage file.
Here's the problem: the partition's size.
I know that this file is exactly the same of my RAM amount: 4 GB.
However the Finder's "Show information" panel says that it's arount 4.3 GB! Which one do I have to trust to?
And if it isn't enough, I know that each partition retains a 10% of its size (even if it's tunable in a second moment with
tunefs); so I'm able to use (by default) only up to 90% of it.
I'm not expert enough to know if the HFS+ journaled filesystem will place any additional (hidden) file, but I suppose that I'm on the right way… can you tell me something more?
I really appreciate any help you can provide.
