This is on the RE, which is just standard Intel x86 stuff (or IIRC ARM
for smaller stuff?).

I think with FreeBSD-based Junos, Juniper forked their chosen FreeBSD
release and made a bunch of customizations.  That means every time they
need to get to newer FreeBSD (for newer hardware support, newer
features, etc.), it is a major operation.  With Junos Evolved, it sounds
like they're going with somebody else's distribution (Wind River) and
adapting to fit it.  Then when they need new support, they just get the
latest release and go (somebody else does all the hardware work).

It's my understand that the Linux kernel tends to have broader support
for new hardware than the FreeBSD kernel, but I haven't really looked in
a long time (I run Linux, not FreeBSD, so I could be wrong).
