Fifteen years of NetBSD

Note, "has become known as" isn't the same as "is".  NetBSD was once the most widely ported
OS, and NetBSD fans cling proudly to that memory.  Those who achieved it are justified in
their pride at it.  It might point up a failure in marketing Linux, among those casting about
for a kernel to run on their exotic hardware.  However, nowadays one chooses hardware
according to what one can run on it, and it's hard to find anything Linux isn't ported to, so
that's not an issue.  

Another concern is what license restrictions might apply, and NetBSD still has it all over
Linux there.  However, that doesn't seem to be much of an issue for most, because most don't
differentiate themselves by their kernel modifications.  A place where one might expect to
find license restrictions affecting a rational choice would be in hardware- accelerated router
hardware.
