Great!

This step should not be necessary. You're probably forgetting to call
`depmod -a` after installing the module. This is needed to ensure that
the right module aliases and dependency information is generated, so
that the module is _auto-loaded_ when users run `ip link add wg0 type
wireguard`.

Awesome!

Okay. Well, keep in mind that I publish release notes here and tips to
distributions about any possible build changes, so your involvement or
at least subscription here would indeed be a good thing.

It's certainly not any of the current `make check` or tests/ stuff
that you're currently looking at. Rather, when WireGuard is compiled
in debug mode, if you insert it, then it will go through a series of
self-tests. For more intense testing, involving the userspace
component, there's `make test-qemu`, which builds a kernel and boots
up QEMU... But I suspect this is a bit too heavy weight for a distro.
And besides, it's already being run for every commit for all
kernel.org kernels on: https://www.wireguard.io/build-status/ By the
way -- this uses musl libc, so I ensure it will always run nicely
there.

The only thing remaining in the package is to remove the incoherent
"wireguard-tests" package, which doesn't work in the way you'd hope,
and doesn't belong there.
