From 18306e6fccd6cab57823059b21ba17188a5501e3 Mon Sep 17 00:00:00 2001 From: Easwar Hariharan Date: Wed, 25 Aug 2021 15:43:41 -0700 Subject: chrony: Fix privdrop packageconfig To drop root privileges on Linux-based systems, chrony requires a standard user to switch to and the use of capabilities. Fix up the privdrop packageconfig to account for this.
