The question of reinstalling/downgrading seems to come up every few
months, so I'm offering to play guinea pig on a test system for
suggested methods. So if you have a favorite/workable solution I'd like
to hear about it. In the end, I'd like to test & document a
reinstall/downgrade Ubuntu while preserving /home for Dummies set of
instructions. Note: yes I know that I can do this with a separate /home
partition, but in the end many/most users don't do this upon
installation (nor are there easy prompts in the installers to do the
same), so I'd like to keep to the 'preserve /home' theme.
There are several blueprints & ideas on how to accomplish this:

[Alternate CD: reinstall Ubuntu over existing partition while preserving
/home ]

[How to reinstall Ubuntu]
http://brainstorm.ubuntu.com/idea/5390/
[Offer to create a separate /home partition and use existing ones]
I don't mind testing the above and any other solutions folks have to
offer (it's a slow week in client land). I'd very much like to figure
out how to easily do this with the Alternate CD(s).
Note: Only standard Gnome Ubuntu liveCD & Alternate CD suggestions please.
Along these same lines, sometime back there was a thread "apt-get system
reinstallation" whereby Andy Baxter wrote up a nice howto
https://help.ubuntu.com/community/ReinstallingSamePackages
Note to Andy: I ran across this in my search on how to reinstall
existing packages & this uses Synaptic and seems to be a very easy way
to accomplish the same task:

It is probably not what you want, but, from memory, what I did (in
upgrading from 8.10 to 8.04) was to make a partition on an external
storage device, copy the /home directory (as much as was allowed, due to
privilege) to the external partition, install 8.04 as a new installation
on the 8.10 partition, then copy the contents of the copied home
directory, back to the newly installed 8.04 /home directory, which seems
to have worked.
