From fa177917209e54ec90a52c6475330b97be82a320 Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Thu, 8 Sep 2016 11:57:34 +0200 Subject: mount: add note about another flags for "remount,bind" The man page is talking about read-only bind mounts (-o remount,bind,ro), but this feature also works for another VFS flags like nodev, suid, etc. For example: mount -o remount,bind,noatime /mountpoint is a valid command.
