My internet service comes over a satellite, and with it a relatively
small monthly download allowance. Which motivates the following
question.
Once I have installed a new disto and downloaded the RPMs that I use, is
there a procedure by which I could gather together everything that I
have added, so that I could transfer the files (RPMs, or whatever) to
a local system, without resorting to the internet? (Or, at least, to a
significant amount!)
Is the "local system" identical to the one where you did the initial
installation?
In a former life, with RHEL versions 4--6, I used a local mirror for the
packages needed to support our use cases. When there were updates,
they appeared in the mirror and systems updated from there. I don't
recall there being a lot of guidance for creating a local mirror, more a
matter of trial and error to get a local mirror working with a small get of
packages.
seems to be roughly the same vintage. The example uses a .xml
list of packages which you could adjust to what is needed at your site.
I also had a mirror for Ubuntu. I recall using rsync excludes in
a mirror script, but that may have been used for Ubuntu.
