Of course all such things are relative - but in my case the HDs on which
I installed 10.10 as a clean install are sitting in cradles and
therefore were used on the *exact same* computer on which I then tried
to install Maverick as an upgrade - AND on to HDs which have faster
seek-times and also with 8X the cache size onboard the HDs contaning
Maverick itself.....but this is of little consideration.
I always try to keep all my installations of Ubuntu the same but have to
admit that the new installation of 10.10 did not have all the packages
installed as the ones I have on the "main" system- for example, I did
not install K3b or K9Copy. Perhaps this may have made a difference? Dunno.

Thanks for the tip.
But I don't really think that I will be doing an "upgrade". I will
simply do a clean install.
From where I sit, it would be a lot quicker. But that's from where I
sit :-) .

The packages may be removed, but what about the config files in, say,
/home and wherever? I've seen posts which suggest that such files are
not removed and may cause system hiccups.
 The Synaptic Package Manager has 2 options for a package: Mark for
Removal or Mark for *Complete* Removal. Why is this so?
To summarise the above: Horses for courses, as I wrote :-) . Do your own
thing - as long as you have some info about what you are about to do :-) .
Went to a discount massage parlour the other day. Wasn't 'til I paid me money that I found out that it was self-service.
