mount and /proc/mounts showing different outputs

0

I have the following line in my /etc/fstab on three of my slackware servers:

tmpfs            /dev/shm         tmpfs       rw,nodev,nosuid,noexec 0   0

All three show the mount options correctly in /proc/mounts:

tmpfs /dev/shm tmpfs rw,nosuid,nodev,noexec,relatime 0 0

Two of them show the correct options with the mount command:

tmpfs on /dev/shm type tmpfs (rw,nodev,nosuid,noexec)

The third one shows different options with the mount command:

tmpfs on /dev/shm type tmpfs (rw)

The only difference is the third one is at runlevel 4 while the other two are at runlevel 3. Any ideas on why the third one is showing two different mount options and which one is the correct one?
