I was thinking it does now, but I wasn't sure :)

You're supposed to be able to boot with no other partitions mounted
than the root fs. That's why there are directories like /sbin and /lib
(which you're not supposed to put onto other partitions). If you can't
boot without /var being writable, there's something wrong.
If you don't have /var, not everything will function as intended, but
that doesn't mean that you couldn't boot without /var. You can do it
for testing --- if you can boot without /var, there must be something
going wrong during the boot process when the root fs starts out being
mounted ro.
