I've just released version 1.11 of the Bubbagen live-USB image for B3 on GitHub.
Because the new Gentoo profile defaults to building position-independent executables and this may lead to incompatibilities with non-pie libraries this is a complete rebuild of the Live-USB. If you are already running Bubbagen and like to migrate to profile 17 as well I suggest you take your configs and move them to this new release rather than rebuild your world yourself.
Following up on Sakaki's kexec kernel starting method this release now also features a second stage bootloader to load the final kernel with a configurable command line. This second stage bootloader was in fact designed from the ground up, because Sakaki's kexec loader left my B3 (with the older U-Boot 2010.06-rc2-00064-gf41e8d8-dirty) without network. If you like it will allow you to use Sakaki's kernel package though, but you should note that Sakaki's kernel thus far does not support systemd init system so you can only do that with the OpenRC version of the Live USB. Please reference the directions in /boot/boot.ini on how to make the bootloader select a different kernel.
Sakaki publishes a binhost that can help you keep your instance of Bubbagen up to date. The Live-USB is not subscribed to that binhost, but you can add it yourself by referencing this topic. To fetch binaries from that host run emerge with `-g` or `--getbinpkg` option. Do note that because the Bubba UI requires specific USE flags on some packages emerge may disregard some of the available binaries on that binhost.
- Changing the network profile may completely destroy networking on the B3 if you have wifi enabled or added custom interfaces and/or bridges. If you need to change the profile please do so before making any changes to the default network setup and then never touch it again.
¹) Some packages withheld due to patent restrictions or because the newer versions are incompatible with core Bubba functionality.
