The installer stops the installation process for
RedHat 6.0 during FTP installation. It waits then
for a permission to try to reconnect to the FTP server.
This should be done automatically with a notification
after some limited number of failures.

The reason is that unattended installation always
fails if big partitions are checked for bad blocks
in the installation process. Then, usually, the timeout
of the FTP server is exceeded and the server closes
the connection. When the installer later tries to
retrieve the first package, it stops and waits for
user input for a reconnection try. This is subotimal
since it makes unattended installation (after answering
the initial questions) impossible and enhances the amount
of work needed for installing many machines significantly.
