Ok, now that I know I can netboot my 5000/20 off my Win98 
box, I am in a bit of a problem:  the machine has only a 512MB HD. 
When I ran 1.4.1, it seemed to be plenty for my small needs:

Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/rz0a       31671    23465     6622    77%    /
/dev/rz0d      296342   244101    37423    86%    /usr
/dev/rz0f      118590     2311   110349     2%    /home
kernfs              1        1        0   100%    /kern

I do not run X in that machine, but I was running apache, perl, and 
would like to run php, ssh, and those little odds and ends.  I plan 
on running netatalk so if I need to download stuff off the net, I can 
mount my user directory (off /home) in the Mac and download straight 
like that.  Does that make sense?

That said, I would like down the line to upgrade its HD (even though 
I do not even have a HD braket for the poor thing!).  If I do so, 
what would be the most painless way to move everybody to the new HD 
so I can then boot from there?
