can already run a number of Linux distros. Martin Michlmayr has posted a
simple how-to to manually install Debian on the SheevaPlug here
http://www.cyrius.com/debian/kirkwood/sheevaplug/ and a fast growing wiki
also exists here http://plugcomputer.org/plugwiki/index.php/Main_Page
Brian also posted in the forum on how to go about using Optware on the plug

It happens that the industrious people at the Slackware family of sites have
successfully ported that distribution over to this particular platform. This
therefore concludes my efforts to be porting Slackware to the NSLU2, but at
some point I will be obtaining one of the units, probably also a developer's
I'll probably continue to be here so as to provide advice and everything

> Also, it would be great to hear how others are getting on with theirs.I've had mine for a while now, and it's quite happily running the
www.cowlark.com server stack running off a home made SSD made up of USB
keys. It's a decently powerful server (although Java on it is a pig ---
the only JVM I've found that will run servlets is OpenJDK, which is
strictly interpreted on ARM and rather slow), and it's really nice to
see the stack of hardware with no moving parts.
However, that's not to say it's problem-free. In particular:
- - the default u-boot's USB implementation only slightly works. It can
take minutes to probe the USB tree, and it's *extremely* unreliable
loading kernels from USB. In particular, it'll just refuse to touch
certain USB keys, and can get fatally confused by certain combinations
of devices. (I applied the u-boot upgrade that enables booting of the
MMC card, which solved all my problems.)
- - The SheevaPlug's USB hardware is generally a bit dodgy. I run RAID0
with 4x16GB USB keys; it took some time before I found a hub that worked
reliably for this, and even then, some devices behave generally funny (I
use a USB ethernet adaptor for my internal network, and it's got a bit
of a tendency to fail under load). Speaking to an engineer who's worked
with Marvell SoC devices, apparently most of them suffer from this.
- - Aside from hardware issues, the SheevaPlug is extremely limited by
only having one USB port. This is very restrictive to I/O throughput.
RAID5 on four devices is basically infeasible; there's just not enough
bandwidth available (RAID5 on 3 devices writes at ~20MB/s. RAID5 on 4
devices writes at 0.5MB/s). You may want to consider an OpenRD, which is
twice the price and still has support issues but does at least have SATA.
Of course, I'm running mine as a full server off an external hard drive.
If you're want to use a cut-down system running off the internal flash,
a lot of these problems go away.
