sys-apps/iproute2 is not on the LiveCD yet. Would be nice if we can include it with 2006.0 as it gives far more network configuration options than sys-apps/net-tools.
Bleh... I meant to add this to amd64/x86 this release and it totally slipped my mind. At any rate, I've added it to my local specs so it'll show up on the next release.
Doesn't matter. At least, I added it to the ppc-CD ;-)
This was on every CD (except sparc) for 2006.1 and has been added to sparc for 2007.0...
