(sorry if i do some mistakes, i don't speak english very well)

In fact urpmi & apt are not specially for users with nice PC and a lot of RAM 
& HD space, they work with the command line and don't need a lot of RAM (8MB 
is fine).

The problem come from the packages. The dependencies must be handled more 
efficiently.

You want to use the actuals redhat packages on a small PC but they are not 
appropriate. If you want to optimise the softwares to run it on a old PC you 
need to modify some RPMs.

urpmi & apt are just tools which made your life more pleasant.

Perhaps you will say it can be a heavy work, but we don't have thousands of 
packages and we don't need to modify all the packages, some of them are done 
very well.
You can also say that the work will be repeated each time a new version come. 
However it is rare because a big part of the new softwares are to fat to run 
on 8MB of RAM and the work we have to done is to update (bugs, security) the 
packages we have modified (not all the packages).

To conclude, i think that modifying the needed RPMs is a better solution than 
ignoring urpmi.

We can give to RULE a real optimised, easy to use & install system.
Thanks to everybody, i love this project :)
