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.
Scott

Anaconda picks the package order based on priority settings, dependency
processing, etc.

There is a file (comps-CENTOSxxxxx.rpm) that world normally be on
CD-4 ... it is moved to CD-1 because it is part of every install and we
would like the minimal install to be self containing on CD-1.

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.
