Is NetBSD better than Linux? Some people think so, which would be kind of funny for all the companies who’ve stalled new features for a year because they’ve been migrating products from VxWorks to Linux.
What do we mean by better? Here’s a clue:
While NetBSD uses the GNU toolchain (compiler, assembler, etc), and certain other GNU tools, the entire kernel and the core of the userland utilities are shipped under a BSD licence. This allows companies to develop products based on NetBSD without the requirement to make changes public (as with the GPL). While the NetBSD Project encourages companies and individuals to feed back changes to the tree, we respect their right to make that decision themselves
That’s a very big deal. It also emulates Linux and is extremely portable. See BSD forums.
