Get packages from stabele tree via sysinstall

[Михаил Кипа]

I want to install precompiled packages via sysinstall. I have update my 
6.2-RELEASE system with cvsup to 6.3-PRELEASE. Now I want to use sysinstall to 
install precompiled packages, but I get an error " Can`t find "6.3-PREREASE" 
on ..." (I use ftp!). So what release name I shoul use to get packages from 
6-stable package collection?
