updating FC4 -> FC5 remotely (no CD of any kind!!)

[bruce]

hi...

given the issue of using yum for an install, i'm trying to figure out how to
effectively update an FC4 to FC5 without using a CD (either ISO or
rescueCD). i've seen articles stating that you can do a FTP/NFS install, but
that you need a 'boot' disk...

is there a way to do the update/install without using any kind of CD...

thanks
