Correct.  You can create an in-memory startup script to do tunnel
configuration, as well, with something like this:

(make script as text file in /tmp; for example, I'll use /tmp/mystartup)

$ nvram set rc_startup="$(cat /tmp/mystartup)"
$ nvram commit

As an in-use example, the contents of one such script I use is as follows.
Note the explicit deletes, because the rc_startup can be run in a "warm
boot" reset mode, where the interfaces are already up.  I didn't bother
masking any data from this list post, since anyone could look up my
addresses via my Received: header, DNS, and traceroutes.  <g>

(Though I don't use 6to4 locally, I do have an outbound 6to4 interface --
something I recommend for all tunnelling users, so that 6to4 clients can get
packets originating from your network more reliably/quickly.)
