But you never tried uninstalling GNOME as advised. Solving the general
proceeds from solvng the particular.

You lay out the problem clearly. There is no silver bullet. You cannot
always be sure but you can imagine biting it. Trust the packaging system
and your own judgement.

What you're saying here, I'd never noticed anything beyond that the
"set to manually installed" message occurs to packages I am, in fact,
manually installing.. It never occurred to me to ponder that packages
might come out of the box that way and that there might be a reason
for them to do so.

That's why I chimed in with my part again. Can't remember what you
said the other day, but it helped trigger the thought process to
connect this all directly to the "set to manually installed"
advisement I (regularly) receive from apt-get. It's a no-brainer to me
to feel that there is surely some predictable purposeful purpose for
the *auto*magically generated "set to manually installed" feature I
accidentally trigger (regularly). :)

Thanks for you insight. As has been to date, this is an "of least
concern" kind of thing for me because nothing within my own system
seems affected, either positively or negatively. My instinct has been
to a-sume maybe it was a feature that proved of significant value to
practicing developers.... or something like that... there. *grin*

The other day I commented that I played along with this thread by
testing apt-mark against what I've observed while installing packages
over time. That observation was that apt-get automatically marks
packages as manually installed without being proactively told to do so
*IF* one (accidentally) installs a package that is currently up to
date on upgrades..

Note: While I was typing the above, it came to mind that maybe that's
a purposeful feature that happens because I most frequently perform
"apt-get install" instead of "apt-get upgrade" (k/t managing limited
resources).

Part of what I shared in my previous related comment is that I see the
following when accidentally using "at-get install" on a package that
is already up to date:

++++++
libchromaprint1 is already the newest version (1.3.2-2).
libchromaprint1 set to manually installed.
++++++

My observation the other day was that once that occurs, apt-mark then
understandably and immediately adds that package to any future query
feedback.

An observation today is that you apparently only see that message
once, that being the first time you (accidentally) try to install a
currently current package. That makes sense so that's where tools like
apt-mark come in handy. If you miss that "set to manually installed."
advisement during that single instance when it occurs, tools like
apt-mark have your back.

My reaction over time has been that, nope, I didn't want packages set
as manually installed primarily because #1 I didn't specifically
command it to be so and #2 I don't know what that action affects
deeper under the hood. So far it hasn't *appeared to* hurt anything,
and, point blank, there are far more pressing issues needing addressed
in my local, real World community at this moment. #Priorities. :)

#175265 — Re: Manually installed packages

Here you have the answer to your own question.
Use apt-mark to mark the packages you want to keep and all "required" packages
as "manual"ly installed. Then mark all other packages as "auto".
Then let
  apt-get autoremove
do its work.

After that, use e.g. aptitude to remove remaining configuration files with
  aptitude purge '~c'

jvp.
