These 3 things don't play well with a Linux ecosystem, as you might know.

It worked alright, I just meant that running it on thousands of personal computers using dial-up to the internet is a badly designed network for a cluster. -- Joost

In any case 'cryptsetup -y luksAddKey /dev/sdaX' allows you to add a passphrase in another slot - can't recall how many passphrase slots are there without looking into it. Reboot to make sure it works and then use luksDelKey 0, to remove the previous key from slot 0. Also, check gnome-disk-utility which I think allows you to change the passphrase.

[gentoo-user] Clusters on Gentoo ?
Howdy one and all, Many see a world where clusters abound even for the small business and resource capable enthusist [1]. Clusters of old PCs are the norm, but a slew of new extremely low powered 64bit embedded systems, running embedded linux, with ample ram (ddr4 even) and up to (8) SATA-3 ports will undoubtly be the targets of aquistion by hobbyist around the world. Other with more salient goals are sure to follow! For example, we (Gentoo) have just had one of the titans of the embedded linux world, return to Gentoo. Linaro is the default industry group that is leading the charge in new development for linux based embedded system sharing most of their work with the larger open source communities. Thomas Gall aka. tgall is working for Linaro as the acting director of the Linaro Mobile Group [8,9]. Clusters will seemlessly integrate CPUs, GPUs, Arms, FPGA, SOCs and many other instantiations of computational resources, sooner rather than later. The Billion dollar players already run these sorts of amalgamations for a very wide variety of reasons, so why should't the bands of linux_commoners have access to such raw power? [10] In a recent thread (schedulers) it was noted that several folks had interest in clusters (privately operated clouds) as more than a passing interest. Companion projects, such as Apache's Spark [4] have tremendous potential as aggressive solutions such diverse fields as social media relationships, distributed database techniques and new, massively parallel programing paradymes for computationally intensive scientific endeavors, just to mention a few [5,6,7]. So I'm soliciting the readers of this list to post any references to distributed/cluster/cloud softwares/fileSystems they are aware of, have used or would like to see; to guage interest in Mesos, Chronos, Spark (apache) as well as all other open source cluster (distributed) systems or tools [2]. My collection of such is sporadic, at best, and serves mostly my math/science needs. Project Aethna, is one of the oldest efforts, still kicking at MIT, the last I heard [3]. Newer/cooler efforts? Hopefully, we can all share ideas and brainstorm about how Gentoo users can lead the pack of linux distros into this brave_new world.

Walter, Thank you for the link, that is great info! Because this is done independantly of the GUI, I don't think it'll set up an icon automatically. Yes I agree. I am still curious what is the mechanism that causes icons to appear on the desktop of popular GUIs. I suspect the answer involves the magic of policykit/consolekit/dbus/hal/gvfs/gnome-vfs/fuse/hotplug/udisks/etc. Thank you, Chris
