If you have, I must have missed it.  How would I clone all the
configuration?

Are you seriously expecting me to spend about EUR 200 to buy VMWare and
to somehow switch my system over to a VM just to test if upgrading
Fedora would work and then to switch it back to what it was to do the
actual upgrade?  Or to spend a couple days to install Fedora or
something else on a spare disk, get a VM to work, somehow transfer my
system or all the configuration into a VM sufficiently similar to the
actual system, just to see if upgrading might work?

That would be ridiculous.

You're wrong.  Just take, for example, a Linux kernel from 1995 and
compare it with one from 2013.  How much functionality has been added,
how many more lines of code are part of the kernel from 2013 compared to
the one from 1995?  Do the same with other software that still exists,
and even though it doesn't really give you a good picture, you'll be
surprised.  How many different CPUs are in use today, how many different
hardware combinations?  Compare that to what was available in
1995.  Compare the functionality some software like Libreoffice provides
today with what it's equivalent in 1995 provided.

Look at graphics cards and compare recent models of today with those
that were recent in 1995 and try to tell anyone they aren't any more
complicated today than they were in 1995.  Same goes for other
hardware.

You'll probably find that quite a lot of now common hard- and software
is so complicated that it would have been impossible to manufacture it
in 1995.

Then make a list of soft- and hardware that wasn't commonly used or
didn't even exist in 1995 but is common today.  Look at a web browser
from 1995 and compare its complexity with one from 2013 and try to tell
anyone that software hasn't become more complicated since 1995.

You must literally be living in a different world than I do, it's
obviously more than just having resources at your disposal most ppl
don't have.  Did you have the hard- and software for your VMs in 1995?
Since nothing has become any more complicated or more complex, you must
have had them already because there isn't any reason not to.

Ok, so you are denying the facts or running "yum update" is a major
mistake --- or I have some strange virus that changed grubs
configuration.  Do you have any idea as to how I can find out what it
is?
