Subject: [PATCH v3 10/10] gnu: Add nebula.

From: Dominic Martinez <[email-masked]>
Date: Mon, 4 Apr 2022 15:32:08 -0400

* gnu/packages/networking.scm (nebula): New variable.
---

I tried to modify the description to more accurately describe the difference
between Nebula and other, distributed overlay networks currently on Guix like
yggdrasil and gnunet, but I'm not sure I did a good job.

I also wasn't sure whether to remove the blobs in a phase or source snippet,
since existing packages seem to do both. I opted for the snippet so that the
blobs would never touch the source definition.
