Hi,

i just tried to put the in installcd iso image on my usb stick and boot it through grub. works fine, except that it doesn't find the usb disk as a boot medium

it does try /dev/sda1 - but can't read it because usb-storage has not been loaded.

Could not find CD to boot, something else needed!

is the message.
when dropped to the shell i can do 

modprobe usb-storage and access the device, so i guess all that is needed to make this work is adding the 'usb-storage' module to the list of modules to modprobe a little earlier on.

BTW: is there a way to continue the boot process after manually mounting the stick?

thanks

First, bugzilla isn't a support forum. You should know better.

Second, we don't officially support this method.

Third, I'm pretty sure usb-storage *is* loaded, or you wouldn't have /dev/sda1 at all. What probably happened is that you used 2006.1 as a base, which has a "bug" in genkernel which only tries to mount the boot device as iso9660, which a USB stick very likely isn't. If you are using the LiveUSB guide, you ignored the nice little warning in red:

Warning: This guide is designed only to be used with Gentoo 2006.0. Do not attempt to use a 2006.1 CD or newer; you will end up with an unbootable USB disk.
