will configuring network allow me to install *updated* packages right from the start?

[Robert P. J. Day]

sorry if this is a trivial question -- i'm just about to read
the install guide end-to-end and it might be in there. if i configure
a wireless network early in the f19 installation process, will that
support installing the updated versions of the packages, rather
than making me do a sizable "yum update" post-install?
