Ever used an rpm based distro? rpm is a terrible package manager IMHO. Many dependency problems. Also Mandrake is the slowest moving Linux I've ever seen in my life. Personally I would never use it.

And I think we must device some solution like what if it stores all the files on to the HDD during Shutdown and then again retrievs them to ram during the next run. the whole trouble will be solved

And I think this may not be a very troublesome solution.
I guess I don't understand what the point of a live cd is if you want to install things to the hdd. Why not just put an OS on the hard drive then? You are aware that it is completely possible to create your own live cd?
