Non-obvious, but it did occur to me as I was writing this comment because of
a related bug in Ubuntu about failing to remount initramfs-mounted
filesystems with the mount options specified in /etc/fstab.

I think it doesn't actually impact the correct design here.  Either your
mount does have a compatible set of mount options, in which case you don't
need to do anything; or it doesn't, in which case a remount is the correct
course of action and if it fails, it fails.  The proper course of action for
the admin in the case of a mismatch is the same, no matter how this is
handled within the lxc environment - it needs to be fixed in the
configuration outside the container.
