[gentoo-user] Iron penguin on usb?

[James]

Hello,

Ok the latest release of livedvd is here:

https://www.gentoo.org/news/20140826-livedvd.xml

So my understanding is you can put this on a usb stick. Run
gentoo live, download packages, set flags, install packages
and save them to the USB stick?  So it's a portable  gentoo
workstation on a usb stick? 

https://wiki.gentoo.org/wiki/LiveUSB/HOWTO


Are these the best instructions to follow to createa usb bootable
live gentoo image?  It has to be able to install new packages and 
save those to the usb stick.

I remember some time back (Neil) mentioned a package I was
not aware of (and naturally cannot remmber the name of) that
made creating USB bootable, usable, images on a usb stick
straightforward?

It even handled grub2, uefi and such?

suggestions?
