        It's 138M  of a 120G hard drive, which is probably about 60M
        more than I'll use. (assuming that I don't put more in root than
        I did with FreeBSD 4.x)

        all my vinum volumes are working fine with two exceptions, 1 the
        swap volume (known problem, at some point in the future I will
        cvsup, make world, etc and it will be fixed, let me know if
        there is any data you would like from this system) and I would
        like to boot from the root volume. which is currently d:
        
        Can I just:
             1.  s/4.2BSD/vinum/ 
             2. transpose a: and d: (if I do this will I have to rm and
                recreate the volumes?  Not a problem I just can't figure
                it out)
             3. Do I then just reboot? It would seem that I need to
                install a boot loader some which way. With
                /stand/sysinstall fdisk? or something else?

        Thanks, I've printed it out and will read it over. (probably
        many times)
