How do I make a "filesystem in a file" ?

I also had a couple of problems: I backed up everything in my "/" 
partition inside /home. Then I tried booting with the System Rescue CD 
or Knoppix. In the first, I couldn't access any of my permanent 
partitions. In the second, I could only mount them as "read-only", so I 
would not be able to restore the "/" partition after resizing it, or 
would I? I mean, I must be able to read/write there after I re-create 
it, don't I? And how am I going to define the mount point as "/" after 
re-creating it?

You see, I still have a lot to learn. I'm starting to believe that this 
is just too much for my present knowledge, and maybe I should just 
"patch" things up with symlinks to somewhere in /home, at least untill 
it's time to reinstall the whole system again... (I should probably do 
it in about a year max.)
