From 5753fc14f5a24b2c4d5f4c76ed22d28a1be67c2a Mon Sep 17 00:00:00 2001 From: sterni Date: Thu, 20 Oct 2022 15:46:40 +0200 Subject: refactor(nix/dependency-analyzer): use unsafeDiscardOutputDependency Turns out that pathContextDrvPath already exists as a builtin which is very convenient. Actually somewhat embarassing that I missed this for so long.
