How to work with /run in Ubuntu?

Question

ubuntu

Good afternoon!
Today I dealt with one VPS on Ubuntu 14.04
So, by default, the mounted partitions look like this:

df -H
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        43G   25G   16G  61% /
none            4,1k     0  4,1k   0% /sys/fs/cgroup
udev            1,1G  4,1k  1,1G   1% /dev
tmpfs           210M  345k  210M   1% /run
none            5,3M     0  5,3M   0% /run/lock
none            1,1G     0  1,1G   0% /run/shm
none            105M     0  105M   0% /run/user

And while /var/run is a symbolic link to /run
In /etc/fstab there is only one entry that mounts /
In /etc/mtab there are options with which /run is mounted

tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0

And the question is - how did I mount /run on tmpfs? What demon mounted it?
