Johnny, Thanks for the thorough explanation. That makes a great deal of sense as a 1-disk install is very desirable for many people. Thanks.

If we did not do this, a minimal install would require downloading disc 1 and disc 4. It (comps) gets installed at different times in the install, based on what packages you have (and it's calculated order in the install) ... and during that time, it will ask you to put CD-1 back in. Depending on the install you do and the packages, it may come after CD-1 is normally done. We believe one switch during install is better than 2 discs for every install, even a minimum one ... so that is why it currently works that way.
