I tried to remount a filesystem by running this command:
mount -o remount,ro node.example.local
...and found that "remount" had shown up as a NFS attribute:
mount |grep -i "node.example.local/share"
node.example.local/share on /mnt/mountpoint type nfs (ro,remount,soft,addr=18.104.22.168)
Why does it say "remount" in the NFS attribute set? I've run this kind of command a bunch of times before, but never seen "remount" showing up in there.
