gentoo-b2-overlay

Gentoo overlay for the Excito B2 miniserver.

List of ebuilds

• sys-kernel/gentoo-b2-sources patch
• Provides a full set of Linux kernel sources, with both Gentoo and Excito B2 patches applied.
• sys-kernel/buildkernel-b2 source
• Provides a script (buildkernel-b2(8)) to build a bootable Gentoo Linux kernel for the Excito B2, targeting either HDD or USB deployment. Can be used on the B2 directly, or on a Gentoo PC (when cross-compiling via crossdev). A manpage is included.
• sys-apps/b2-init-scripts source
• Provides a set of simple init scripts for the B2 (to turn on the LED on boot, copy across network settings when booting etc.).
• media-libs/libjpeg-turbo upstream
• Provides libjpeg-turbo-1.5.0.ebuild and libjpeg-turbo-1.5.1.ebuild with --disable-simd explicitly set; build fails on the B2 otherwise.
• net-wireless/hostapd upstream
• Provides hostapd-2.0-r1.ebuild; this has been removed from the Gentoo tree, but newer versions require (patent-protected) EC from the openssl library, which is incompatible with the bindist USE flag.

Installation

As of version >= 2.2.16 of Portage, gentoo-b2-overlay is best installed (on Gentoo) via the new plug-in sync system. It will supply a repository named gentoo-b2

The following are short form instructions. If you haven't already installed git(1), do so first:

# emerge --ask --verbose dev-vcs/git 

Next, create a custom /etc/portage/repos.conf entry for the gentoo-b2 overlay, so Portage knows what to do. Make sure that /etc/portage/repos.conf exists, and is a directory. Then, fire up your favourite editor:

# nano -w /etc/portage/repos.conf/gentoo-b2.conf

and put the following text in the file:

[gentoo-b2]

# Gentoo overlay for the Excito B2 miniserver
# Maintainer: sakaki (sakaki@deciban.com)
 
location = /usr/local/portage/gentoo-b2
sync-type = git
sync-uri = https://github.com/sakaki-/gentoo-b2-overlay.git
priority = 50
auto-sync = yes

Then run:

# emaint sync --repo gentoo-b2

If you are running on the stable branch by default, allow ~ppc keyword files from this repository. Make sure that /etc/portage/package.accept_keywords exists, and is a directory. Then issue:

# echo "*/*::gentoo-b2 ~ppc" >> /etc/portage/package.accept_keywords/gentoo-b2-repo

Now you can install packages from the overlay. For example:

# emerge --ask --verbose =sys-kernel/gentoo-b2-sources-3.18.2
