New system - go for 9.1+upgrade - or go for 9.2-RC4?

[Ewald Jenisch]

Hi,

Since I'm about to set up a new system from scratch I'm thinking
whether I should install 9.1 and upgrade it to 9-STABLE or to install
9.2-RC4 right away.

To be specific:

o) Will upgrading kernel/system using
svn co svn://svn.freebsd.org/base/stable/9/ /usr/src
bring a 9.2-RC4 installed system up to date once 9.2 final is released?

o) Is it possible to install ports using "portsnap fetch extract" and
"pkg_add -r..." on a system that was installed using the 9.2-RC4-CDs?

Thanks much in advance for your help,
