Implementation: Postinstall

You need to bootstrap getupdates via HTTP/FTP/NFS
We read config options from /proc/cmdline: options are passed to install kernel (via syslinux / other boot loader)
Some getupdates logic in postinstall to get load options, use them to retreive getupdates and its tools, install them on disk, and save boot options in /etc/sysconfig/getupdates
Distribution specific, but needs to be run in a chroot after the distro's install has completed (%post in a Red Hat kickstart file)
Install getupdates ASAP so that it can continue the install if machine crashes or gets unplugged during postinstall
