A good idea there. That will avoid most of the 'downloading again'
should things go south. An 'update' in a few days would only be recent
changes. It is not uncommon for there to be 50, or so, packages a day.
It all depends on how much of what you have installed.

I would. I have, as a time with nothing to do thing, installed a
release. Updated it to current. And then 'changed' it to Rawhide and
updated it then. And I had not problems.

You had said 'laptop' and they are noted to not have large harddrives.
It sounds as if you will not have that problem.

Sorry. Did not mean to be condescending.  ;-)  I have seen many
'experts' that only thought that they were experts. Many who were great
with a GUI to look at and lost at the CLI. There was a thread a while
back that had a 'many years of experience' guy that could not maintain
his network because he could not log into the GUI as root. He could
have. If he had that much experience.  :-)

I don't know about the bork part. I really do believe that most
'problems' are self inflicted. Third party site packages is a big one.
Odd hardware is another big one. By 'odd' I mean not well supported.

Good luck.
