Im sure you have done enough of your own homework on the subject
. But for the sake of discussion I wanted to throw out a few links worth looking over that could help anyone learn how good partition scheme methodology can save space.
Pretty good, as stated in the article it references "the why not the how":
Again more of a why and not so much on how, but much more in depth:
Now making all these partitions for each aspect is argued to have its own space problems. It is said that each partition will have certain amounts of wasted space. But I think the wasted space is less than that of what would be consumed by the system if allowed to have all the space it wanted. Logs, dumps, etc. all keep filling up if not managed. Then to keep in mind if you wanted run the fsck command, the smaller the partition the less time it would take to run through.
Also another thing that may be debatable. I have read that swap space was created for linux during a time when ram / memory was hard to come by. What with older machines most had at best 256mb or 512mb? Somewhere around there. So the swap was utilized as a way to create the ram space that the sticks could not offer. Today I think it is a waste to have a swap space. That is unless you are dual booting and / or have many users.

I hope this is of some help and use.
