You also don't want the checking to be too tight, since it makes upgrades
when you're using OS packages more difficult if the versions have to match
exactly and normally it works fine.  Usually the kernel module is in its
own separate package, and since you want to be able to have multiple
kernel modules for different kernels installed at the same time, it's a
bit tricky to ship afsd in the same package as the kernel module.

Ideally, the interface should be backward-compatible, since it's not like
we change the parameters often, but that may be too much work.
