Summary: Ebuild and basic instructions on getting BOINC and WCG to play nice with Gentoo Linux.


BOINC support is present within Portage; however, the latest version, stable or unstable, is 4.7.something. Here's how I got running with BOINC 5.2.8 and WCG. I'd didn't try activating the GUI or anything, just the CLI version.

Step one:
Get files. I've upload the copies of the ebuild, init, and conf files. Get a tarball here: http://www.d-struct.org/projects/gentoo-boinc/gentoo-boinc.tgz

Step two:
Put files in the right place. You'll need to create the proper directory structure in your poratge overlay. For me, that's:

/usr/local/portage/sci-misc/boinc/


Put the boinc-5.2.8.ebuild in there. Copy "boinc.conf" to /etc/conf.d/boinc, and "boinc-init" to /etc/init.d/boinc.
Step three:
As root:

ebuild /usr/local/portage/sci-misc/boinc/boinc-5.2.8.ebuild digest


Step four:
Add "sci-misc/boinc ~x86" to /etc/portage/package.keywords (or your own favorite method of unmasking unstable packages).
Step five:

emerge boinc -pv


Check to make sure it's picking up the proper version. In this case, you're looking for 5.2.8.
Step six:

emerge boinc


Step seven:
Attach to WCG.

/etc/init.d/boinc attach


Enter your information when prompted. Alternatively, you can simply tar up your previous boinc directory, which would be $HOME/BOINC if you followed the WCG instructions, and dump it into /var/lib/boinc. Make sure the files are read/writeable by the "boinc" user.
Step eight:
Start up BOINC

/etc/init.d/boinc start


Step nine:
You're done. Post feedback and comments. Improve on the code - I just did the bare minimum to get it running.
