From 94b56d753927672bb4a0128fff22f7ca3a129b2f Mon Sep 17 00:00:00 2001 From: Juan RP Date: Fri, 7 Feb 2020 09:16:57 +0100 Subject: [PATCH] alternatives: do not remove symlinks if provider != target pkg. This fixes the keep_provider_on_update test case, submitted by @st3r4g via #219. While checking for obsoletes make sure current provider also matches the current target pkg.
