    The doFS.sh script (even in 4.x) supports both vn(4) and md(4).

    One thing you'll definitely need is to install the Perl port in
    LOCAL_SCRIPT. Mounting /dev (much like the RELENG_5 and HEAD
    versions of release/Makefile do) will also be needed. Note that
    you should be using the 4.x version of release/Makefile* to
    start "make release", and use WORLDDIR to point to your
    /usr/src, something like this:

            cd /tmp
            cvs co -rRELENG_4 -l release
            cd /usr/src/release
            make -f /tmp/Makefile release ...

    P.S. Last time I tried it (more than a year ago), it worked.

    Cheers,
