NetBSD is a wonderful OS for embedded applications. Having support for a fully static port (the Sun2 port) and for old, generally slow architectures (m68k, VAX) means performance regressions don't go unnoticed, for starters. I run NetBSD on a system with 24 megs of memory. I don't think this is possible with modern GNU/Linux - one would need an older kernel and something other than systemd, I think.
