I've just released version 1.4.0 of the live-USB image of Gentoo Linux for the Bubba|2 (B2) on GitHub (here). The kernel has been upgraded to version 4.9.16, which is a long-term-support variant. All included packages are up-to-date against the Gentoo tree, as of 25 March 2017. A full package list may be viewed here.
As before, you can burn the supplied image to a USB key (>=8GB, Lexar and SanDisk keys seem the most reliable; please see this note for a quick way to check compatibility), then boot your B2 from it, without affecting any installed (Excito) system on your B2's hard drive. (The compressed image is 354MiB; writing takes between 10 and 20 minutes, depending on your system.) You can even boot a diskless B2! No soldering, compilation or U-Boot flashing is required.
The live-USB may then be used as a rescue disk, to play with Gentoo Linux, or as the starting point to install Gentoo Linux on your B2's main hard drive. Any packages you install, or other changes you make, while running the live-USB are saved on the USB key, but do not affect your existing Excito system, so you can run Gentoo for a while, then reboot back into your Excito system and continue to use it as normal, then boot back into the USB at a later date - any changes you made will still be there when you do.
Full instructions are provided on the project's GitHub page (including how to specify initial network settings, so you can ssh in once booted, and how to install Gentoo on your B2's internal hard drive too, in case you want to do that).
Some other changes in this release:
- The image now has the getbinpkg FEATURE set by default, and is subscribed to my PORTAGE_BINHOST (at https://isshoni.org/b2); I have a B2 setup now to do a weekly genup run, with the resulting binary packages being rsync'd to this host. I can't guarantee to keep this going forever, but it should significantly shorten the future update process, at least for those packages included on the image). Packages not available on the binhost will be compiled locally as normal. If you don't want to use this facility, just edit out the appropriate FEATURES line in /etc/portage/make.conf. Use the provided binary packages at your own risk.
- Migrated from the sakaki-tools-lite tools to the regular sakaki-tools variants (genup and showem).
Have fun ^-^
PS - many thanks to NorseMaN for kindly gifting me his old B2 server, which has enabled me to get this project back up running again.
