Do you have an entry in /etc/fstab for /run?

The first three fields *must* be

tmpfs /run tmpfs

or it will think the filesystem type doesn't match, and do a new
mount rather than a remount.

Are you using an initramfs?  It should already be mounted if so.
And in this situation, it should just result in a remount with
the options from /etc/fstab.  If you're not, it should mount it
in mountkernfs and then remount in mountall if there's an fstab
entry.

This is as documented in tmpfs(5).
