I ran upgrade against a rhl 6.2+ system which happened to have lilo 21.4.2 installed. Since beta2 contains lilo-21.4.1, lilo was not updated. Although the resulting system booted and ran, the graphical boot did not. There was no /boot/message file (part of lilo-21.4.1) although the /etc/lilo.conf had message=/boot/message specified (I am surprised there was no install error). While I expected that lilo would not be update and was prepared for this, it may be confusing to a more unsofisticated user.
