The tail of two systems and one hard drive. I install centos 5 on a HD while it is in a Compaq with 256Mb memory. After install, i am in graphics mode (Gnome) and top reports not quite all 256Mb used. Then I move the HD to a decTOP with 512Mb memory. I am running non-graphics (init 3). I ssh into the unit and top reports not quite all of that used..... So what ate up more than 256Mb memory (X is not running)? Perhaps there is something I did not clean up properly wrt the move.
