Sorry for my poor English and basic question. I'm looking for a plug computer (to made a home appliance). What can i -must- buy ?
Only the plug computer ? I heard it's need to but a developper kit ? Right  Wrong ?

Thanks

Yes, Ubuntu 9.04.
But it's pretty easy to install another distro (Debian, Gentoo, Fedora). I use Debian myself.

I have the same question. Never used a plug computer - but have some exposure to linux.

Does this Sheeva Plug come with a OS pre-installed. Is it good to go out of the box? I basically want to replace my 7 yrs old linux server which just runs a webserver.

Thanks...

Hello sunnyboy70, the SheevaPlug comes pre-installed with Ubuntu 9.04, aka Jaunty Jackalope. This is fine for running a simple webserver. The OS runs from the internal NAND memory though. So most Sheevans use an SD card or an external USB drive to run the OS from to prevent the NAND from wearing out too quickly.

Is this true?  Got a source for this info?  I run from internal NAND, as that is clearly what it's designed for.   If it does mean "wearing out" the internal memory, I would like to know about it..

This is the procedure I followed in order to use an SD card, rather than the internal NAND flash, as the root file system. My reasons to do this are in order to have a bigger root FS (I'm using 8GB), in order to avoid hammering the internal flash and wearing it out, and to make it easy to make duplicate plugs, by simply by duplicating the SD card.

The plug comes by default with JFFS2 and can be replaced using installer alpha-6 with ubifs.
Both those filesystems makes sure to spread the writes over the whole NAND to make it wear our much less. BTW - the same technology is used in SD cards and external USB sticks.
