Support for firewire should be added to the kernel or included as modules so that firewire optical drives could be used for installation. Currently, if the system is booted from a firewire combo drive, the user is dropped to BusyBox because the CD can't be found. This prevents the user from even doing a network installation. Firewire support should be included as modules to open Gentoo to users of firewire hardware.
There is a workaround for this. If you boot from a 1.2 livecd, you can get to a shell, from which you can start eth0, download one of the (1.4) stageX tarballs, and install. I had the same problem as you with 1.4_rc1, but haven't tried 1.4_rc2.
latest experimentals ahve firewire in the initrd to boot cdroms, its untested right now www.gentoo.org/~livewire
ok, this should be fixed from here on in. for comprehensive firewire support, a 2.6 kernel is really needed.
Moving these so we can remove the "Install CD" component from "Gentoo Linux". I apologize to everyone for this spam, but according to the bugzilla developers, this is the only reasonable way to do this.
