From 9f8bda1df9c661fd6b575336ad808bac851b6e66 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Mon, 24 Jun 2024 11:41:53 +0200 Subject: [PATCH] cli/config: replace pkg/homedir dependency with local copy There's some consumers of the config package that don't need any of the other parts of the code, but because of the pkg/homedir were now forced to also depend on docker/docker. This patch introduces a local copy of the function to prevent this.
