We (Seneca OSTEP) are now also operating a second Koji buildsystem, for the armv6hl architecture. This architecture is really of interest only for the Raspberry Pi at this point in time. This buildsystem is accessible on the web at http://japan.proximity.on.ca/koji/
However, to access the armv6hl buildsystem using the Koji command-line tools, using a Fedora client certificate, a bit of a dance is required. This post outlines the steps...
6. Profit! -- You should now be able to issue commands to the armv6hl koji system by typing: armv6-koji command
In due course, we'll get this configured as a standard secondary-arch Koji instance, and you can skip the steps above -- but in the meantime, if you want to help with the armv6hl effort, those are the steps required.
These are my first two books: X Power Tools, a thorough guide to the X Window System (O'Reilly, ISBN 9780596101954) and Fedora Linux: A Complete Guide to Red Hat's Community Distro, a practical hands-on book on Fedora (O'Reilly, ISBN 9780596526825).
Fedora Linux is also available for online reading through Safari and in downloadable PDF format from oreilly.com
