Good :)  Let's test this "use all the defaults" way as much as we can,
so we mimic what a newcomer is likely to do, and so we can easily
document it!

Something seems odd there.  Logically we seem to have the same image,
booted on the same hardware, and the same preexisting disk setup.  So
*why* would that system act differently on each occasion?  It should not
be dependent on the time of day, or small variations in air temperature.

Sounds good to me!

It depends on the owner of the PC upgrading RAM.  Few computers were
sold with 384MB.  But it was fairly common to buy a 128MB machine, and
upgrade a couple of years later when a 256MB RAM module was
cost-effective, so you added a 256MB module to the existing 128MB for a
total of 384.  [ I've seen 1.5GB machines, and 1.25GB machines, caused
by upgrades in the same way -- start with 256MB, and by the time you
upgrade, it makes sense to buy a 1GB moduke, so you add that. ]

If you are techie enough to play around like that, you are probably
techie enough to remember a command :)

Agreed.  I definitely want us to test this... let's see if it helps!
