Do ya think ? ;-)
I know, I don't understand - notice it also wants to REMOVE "initrd-tools", and
"base-config" -- ....there goes the w-h-o-l-e neighborhood too!

Understood and THANKS! ....Warning heeded!
But why/what are the items in parentheses there for ??
Is it telling me that I would _need_ those versions listed in parentheses, in
order to fufill dependencies...or what ?? The versions listed are NEWER than
those - an example is the "initrd-tools" line;
Inst module-init-tools [3.2-pre1-2] (3.2.2-3 Debian:testing)
hmmm...something's fishy here

I see - but does it not know that One _needs_ a Kernel-image ??
Earlier in this thread and starting with a purely Debian Sarge 3.1r1 (and
having ONLY upDated, once a week ) but never; until yesterday that is, have I
upGraded). I upgraded *prior* to adding any "testing" references anywhere on my
system.

I meant the command output of ($ sudo apt-get -s -t testing install hdparm) -
that this will start the chain of events, leading to many woes...

I understand _that_ very well.... I've even managed to allow running any
command as 'sudo' without being prompted for a passwd in the shell all the time
-- by using visudo to edit the sudoers file as root, and adding this line;
$Username ALL= NOPASSWD: ALL
The tricky part was how to use Ctrl+ZZ (or was it Alt+ZZ, or Shift+ZZ) to
actually Save the changes ;-/
Had to read some of the Vi manual to learn that one -- thank you for the
explanation anyway.

Thanks -- that's what I mean about _that_sudo_command (meaning that particular
one -- I guess I was too lazy at the time to retype the whole thing...likely I
was just more involved with trying to understand what's happening - my bad)

I was waiting for that :-p

I see -- Thanks

I see -- now is where I start to get a little into the 'unknown' - I was hoping
to get into compiling my own kernel sometime in the not too distant future, but
for now, I'm still quite a bit green on these things. Trying to understand the
system, the way the OS functions - and how it behaves, can be pretty
challenging, but I'm making in-roads, slowly.

I thought about that - and am still contemplating the move....

Do I understand correctly about "backports" -- it's basically a "customized"
kernel ?
I originally started this thread when I came across this URL link to;
<http://www.ibiblio.org/pub/linux/system/hardware/!INDEX.html>
which is where I first noticed an Updated 'hdparm'...Why do you think it's not
clear about which "version" (sarge, testing, sid) it can be applied to?
Oh...perhaps because it's (hdparm) not a "distribution" (Debian) specific
utility? doh!

Hey -- atleast you stopped this sometimes overly cavalier, wreakless man from
acting too boldly ......and driving off the cliff ;-)
Thanks for your help -- I appreciate it -- plus it gives me more ideas, and
places to look
