I'm bringing up a replacement to a server I have in production  
now.  The new server is a sparc64 (as is the old one), and will be  
running something approximately the head of the netbsd-4 branch, at  
least until 4.0 stabilizes.

   Now that tmpfs exists in NetBSD, I'm wondering if people have any  
thoughts/opinions, hopefully based on a deeper understanding of the  
two filesystems than I have, of which might be better in which  
situations?

   Thanks.  I'm currently only using /tmp on a memory-filesystem, but  
may also move /var/run there, cause I've always liked that idea too.
