From d127f9bd0e7b9b2e0df2de8a2227f77c0907468d Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Wed, 18 May 2022 17:39:39 +0200 Subject: chore(3p/nix): unvendor tvix 0.1 Nothing is using this now, and we'll likely never pick this up again, but we learned a lot in the process. Every now and then this breaks in some bizarre way on channel bumps and it's just a waste of time to maintain that.
