I'm aware that unionfs status and I think it's usable
in 7.x, right?

I was asking about nullfs because the following lines
in sys/conf/NOTES:

# NB: The NULL, PORTAL, UMAP and UNION filesystems are known to be
# buggy, and WILL panic your system if you attempt to do anything with
# them.  They are included here as an incentive for some enterprising
# soul to sit down and fix them.
