Could you rerun your testing after setting sysctl kern.module.verbose?
This should provide extra kernel debug printf() messages...
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
DEBUG: module: plist load returned error 2 for

chariot# df /mnt
