I see that tarfs, a file system which can make a read-only file 
system out of a compressed archive, has been added to FreeBSD 14.0. 
This could be especially useful for embedded work IF one could boot 
from it... and possibly overlay files in it with unionfs to allow 
customization. Does this capability exist?
