Is that supposed to read fileglob? Not that I make head or tail
of it either way -- you're far over my head.

You tell me. I've had the CDs for something like a month, during
which there've bugfixes, security fixes, and God knows what all other
stuff. The iBook is basically my wife's, though I also use it when away
from home. I want her to be able to just sit down and use it, as she & I
both did at the Library of Congress, where we had layer above layer
above layer of skilled and specialized people backing us up. I at least
find linux fun -- when I'm not overwhelmed. She won't.

You can say that again! It was still getting them when I started
this! And that's on a DSL connection. It has stopped now, but without
giving my prompt back; so I presume it's hung, not finished ...

If/when it gets so far? How long should I let it alone in hope
of that? Ten more minutes? A hundred? It's been going something like
half an hour or an hour, and there are tewnty-odd screns of fine print
there now.

I.e., the upgrade is preferable to the update??

Good goddlemityDAM! If it fills *that* up, I'm zonked: 25GB is
the size of the whole YDL installation!

Just type what's in your quotes, and hit enter? It seems
remarkably bassackward -- more sense, if I understand you (and I doubt
that) would be only to take what I need in the first place.
Surely 'yum remove' needs a list of targets? If I knew how to
tell which to specify -- i.e., which I either use, or need available to
be called by things I use -- I wouldn't be asking this. I'm *years* of
work away from being able to read down the list saying "keep this, toss
that, keep this ..."

That would make sense if I had any idea how to do it -- I think
...

Well, I know it's possible to move things from one partition to
another. And I think I have a faint glimmering what a symlink is. But I
have no idea how to *do* either, and wouldn't recognize it if it got
baked into a pie and thrown in my face. For about a year and a quarter
now, I've been spending more time on linux than even an old retired fart
can afford -- and we still have to settle the contract on the new house,
move into it, unpack, arrange our worldly goods, ....

Do I do that -- as I certainly hope -- before I tell it to
install anything?
