Some of you may have heard this or even used it already, but Plugbox Linux is a natively-compiled (on the Sheevaplug) Arch Linux port that used mainly vanilla Arch Linux PKGBUILDs, initscripts, packages, and tools. It works great on all plug computers: Sheevaplug, TonidoPlug, and Pogoplug (probably Ionics plugs as well, we just haven't tried it).
All of the 2,500+ packages we have in our Pacman repository were compiled on a Sheevaplug (well, 4 different plugs...) for optimization and speed. We stick as close as possible to the vanilla (unmodified) PKGBUILDs from ABS.
Of course, it's fully compatible with your usual Arch Linux tools: Makepkg, Yaourt, AUR, ABS, Makeworld, an easy /etc/rc.conf and BSD-style init are fully working on the Sheevaplug.
If anything, it's an extremely easy way to set up a native build environment. You'll master building packages in 5 minutes, guaranteed. It's even easier than ./configure, make, and make install. Makepkg is amazing, and you'd be suprized how fast packages are made (for a 1.2GHz plug anyway). It's a good way to get around setting up a cross-compiler (especially if you don't have a Linux install on your computer).
Installation is simple - download the rootfs below, grab a With-Linux kernel and modules, and just follow the SheevaPlug Installer 1.0. It works great from an SD card, USB, and NAND. SSH is enabled and on by default.
It's far from perfect and we're only at version 1.0.1 and have a lot planned, so feel free to join in! IRC is where the developers mostly hang out, so stop by with questions (and anything else)!Information and Links
