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)
