for the first time yesterday

good to know for future ref

as it turns out, i watched yum operate up to the y/N query to find
pkgs/revs and dependent pkgs/revs; then i hunted down those packages
on the CDs and copied them; i got the lksctp pkgs from an RPM
repository somewhere in the ether and copied them; i used "rpm -ivh
<pkg>" on 6 rpms to change the kernel and add lksctp; now i'm able to
rebuild fedora 11 boxes without net access

i did this once; i repeat the exercise on a second box today and
hopefully validate the process

these particular boxes will operate without access to the Internet and
updating is not a requirement, but again, good to know for future ref.

i'll need some time to learn this but i have an idea of what you are
talking about from research i did yesterday; this, i think, i should
do

nice; a bit over my head but it gives me something to reach for;
besides, experts should not spoon-feed;
