Why Fedora needs so much RAM?

["frank wang" <yixiaodafang gmail com>]

Hi,

I tried to run live CD of fedora 7. In the boot up menu, one item is
run from RAM. It requires 1GB+ memory. I wondered why fedora 7 takes
so much memory. Recently, I am looking for a linux that requires less
memory. Supprisingly, Puppy2 and Damn Small Linux can run linux from
RAM with 128 MB and 48 MB ram.


Thanks

Frank
