My guess would be that since this OS is targetting the least capable
boards that usually only have a very limited amount of flash memory
for storage, a decision was made to make /var a symlink to /tmp. That
way only a single instance of tmpfs is mounted. Creating a /var/tmp
subdirectory that would be practically the same as /tmp might have
seemed odd to the develoers.

But now that I see FHS mandates /var/tmp, I'll try to send a patch for
that.

And by the way, OpenWrt is the correct official spelling.
