Example of bug occuring: 1. Select packages which take up more disk space than you already have. 2. When you are warned about this, go BACK to re-select packages. An error, "Unable to mount..." (something) appears. This isn't fatal, the install goes on as normal. It looks as if the installer is trying to mount a partition that is already mounted. RH6.0/Intel, FTP install.
known bug. Hit 'retry' and you should be able to proceed.
Hitting RETRY does indeed allow the installation to continue successfully, but the error dialog box still allows dread to enter the heart of the user. :-)
