Or how does one generate the dvd iso given a list of rpm files? (Assuming I had a list of all of the needed rpm files).
It would be nice if one had something like "make centos_5.2_dvd_iso" :-)
Check out this link .. it provides all the information on how to do this. I've not tried this with anything more recent than RHEL 3 .. and the example is with RHEL 4 .. so it may or may not work, but it is headed in the right direction.
