wine users - May 2005 - How many partitions is necessary for WIne/Cedega/Crosver?

In the Linux system, there are lots of  libraries, namely /usr, and
they're all by itsel. People say it's not the matter.. Now, to install
these libraries I don'r know if I should mark them individually, or 
should I just tick the /, automatically (without the need of  a
request).

And then there's that other not: would creating a blue partition be
necessary or should I just my login.

Thank you very much
