There are some info during boot (before securelevel is set to 1):

---

Mounting all filesystems...

All file systems (mfs, kernfs, procfs, and ptyfs) are
mounted properly, though.

On multi user, there is no particular info:

---
# mount -t tmpfs tmpfs /mnt
mount_tmpfs: tmpfs on /mnt: Operation not supported by device
# shutdown now
Shutdown NOW!

 :

Enter pathname of shell or RETURN for /bin/sh: 
Terminal type is kterm.                                                 
We recommend creating a non-root account and using su(1) for root access.
# mount -t tmpfs tmpfs /mnt
