+1.
And I cannot understand why ee is not in /rescue.

On rescue, man pages are NOT promised to be read on another vty.
Having modal editors which requires knowledges for their internal
commands only is a huge shame. The first time I installed FreeBSD, I
need to rush to bookstore to purchase a brief command reference book,
IIRC, for vipw (didn't know about ee and how to switch vty ATM).
Of course, having ed and vi (ex) in rescue is nice. But need at least
already-in-base ee, too.

And another aspect. kmods from ports are installed into /boot/modules,
not in /usr/local/modules (IIRC, there was a time window it existed).
Why not /rescue, if there is enough reason?
