Does anyone besides me notice that the more Dave and I argue the longer
and longer the list of extenuating circumstances gets in order for Dave
to continue to be right?

In this email, I'm not right if the data is on separate partitions.

Dave, do you realize how many people, despite advice to the contrary,
put everything on one honk'in / partition? For all those people, I'm
right.

Dave, you're confusing the rule with the exceptions to the rule. I'm
right as a general rule, and you're pointing out all the exceptions to
the rule to try to prove that I'm wrong.

Prove it. If you can code multi-threading SMP block and inode
allocation using a non-preemptive kernel (which Linux is) ON THE SAME
PARTITION, I will eat my hard drive.
