Description of problem:
Under Custom installs, if individual package selections are modified during the "Package Group" selection phase (by 
clicking Details, then altering the checkbox list shown),  those changes are not reflected in the Anaconda-generated 
Kickstart file.  In such a situation, the generated Kickstart file can NOT be used to duplicate the installation process.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1. Perform a "Custom" install of RedHat 8.0.  During "Package Group Selection", click on Details at least once, and change 
the list of selected packages (when choosing packages to select or deselect, try for some without many dependencies)
2.  Complete the installation.  Boot up and save the /root/anaconda-ks.cfg file, and also capture the RPM list, either saving 
/root/install.log, or using "rpm -qa | sort >rpm.lst" and saving the result file.
3. Set up a Kickstart floppy, using the generated kickstart file from step 1 without modification.  Re-do the installation 
using this Kickstart floppy.
4. Boot the re-installed system.  Capture the rpm list using the same method used in step 2.  Compare the 
new rpm list to the original rpm list from step 2.
    
Actual results:
The 2 rpm lists will differ.  Any/all individual package selection adjustments made in Step 1 will have been ignored 
during the Kickstart reinstall, unless those packages were affected by other dependencies.  It is as if these changes 
were not included in the manufacture of the generated Kickstart file.

Expected results:
The 2 rpm lists should have been identical.

Additional info:
If this is actually intended behavior, I would like someone to explain to me why this is the case.  As the ability to 
make such adjustments is rather new (it didn't exist in 7.2, haven't checked 7.3) the most likely explanation would 
seem to be that someone simply forgot to include these adjustments when generating the kickstart file.
