devfs and /dev/fd/3

[Marc Olzheim]

Hi.

I've seen the question once before, but it was not answered (on-list ?),
so now that I run in on it, I'd like to know what to do:

On FreeBSD 4.x, without devfs, the following worked:
( echo foo | tee /dev/fd/3 | tr f F ) 3>&1

It should produce both "foo" and "Foo"

FreeBSD 5 with devfs, however, does not create a /dev/fd/3 upon opening
filedescriptor 3 by the shell, so there's no device to write to...

How can I fix or circumvent this, aside from mounting a ufs partition
with mknod-ed files over /dev/fd ?
