Jim,

Very informative e-mail. The only thing I think you're wrong in is that ValeMount's StarOS software is based on FreeBSD. They used to use FreeBSD and their free floppy/8 mb flash image is based on FreeBSD. However StarOS is based on Linux. It is obvious if you look at the image file - LILO, initrd, bzImage etc ...
