Subject: [PATCH v2 3/4] Revert "systemd: Apply all sysctl settings when NFS-related modules are loaded"
Date:   Fri, 25 Nov 2022 15:06:55 +0100

This reverts commit afc7132dfb212ac1f676a5ac36d29a9e06325645.

The approach caused problems with sysctl from busybox and with kmod as
reported in Debian (https://bugs.debian.org/1024082).
