From afc7132dfb212ac1f676a5ac36d29a9e06325645 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 7 Jun 2022 14:22:11 -0400 Subject: systemd: Apply all sysctl settings when NFS-related modules are loaded sysctl settings (e.g. /etc/sysctl.conf and others) are normally loaded once at boot. If the module that implements some settings is no yet loaded, those settings don't get applied. Various NFS modules support various sysctl settings. If they are loaded after boot, they miss out. So add commands to modprobe.d/50-nfs.conf to apply the relevant settings when the module is loaded. I have placed this in the "systemd" directory because it seemed the least bad choice.
