Re: What is embedded linux ?

It's not a silly question really.  The answer is that they're loaded from a
filesystem as normal, but the filesystem resides on some non-disk media.  Of
course it depends on your application; some embedded systems have a disk, but
many don't. For more info, see the section in the HOWTO at:
    http://members.xoom.com/greyhams/linux/PowerPC-Embedded-HOWTO-12.html

For VxWOrks/pSOS have a single object file.

And the academics used to criticise the Linux kernel for being monolithic! :-).
