[ale] any ALE members familiar with embedded linux?

[cbergeron at dashwerks.com (Christopher Bergeron)]

If so, can I ask you a few questions about embedded linux systems and 
how they differ from a normal linux kernel?

Specifically, I'm wondering about BlueCat and Embedix.... do they just 
offer packages that let you trim stuff out of the kernel, or is there 
more to embedded linux in general that I'm missing?  I don't necessarily 
need real-time OS, but I'm moving into the embedded realm.

Are there any embedded-linux specific mailing lists of note that I 
should join?

Thanks for any insights...
