From 00c8b28c1ae9c01e4d68871b6a6289e5a55e1246 Mon Sep 17 00:00:00 2001 From: Rick Macklem Date: Tue, 1 Dec 2020 23:33:10 +0000 Subject: [PATCH] Improve man page for AmazonEFS mounts. PR#250770 was actually just a misunderstanding of what NFS mount options are needed for AmazonEFS mounts. This patch attempts to clarify the manpage to clarify this. This is a content change.
