I am aware of all of this. I was caught by surprise when my ZFS 
filesystems appeared partially ordered.

I know that / and /dev are mounted by the kernel, and sometime later 
the remaining UFS/ZFS filesystems, and I also have a few synthetic 
filesystems mounted late in the boot process, and the latter ones 
(still) appear at the end of df(1)'s output.

Order has somewhat been restored. Maybe it's no biggie.
