How do you know that the name will be the same? assuming.
Have you tested the yumuptd process to make sure it doesn't crash.
If you make the change pre rc2 install, how do you know which packages you are getting before May 31st (the last 2 days of buggy packages of kernel, anaconda, pungi, etc OR a newer version that has not been compiled yet? And will yet a newer nwer verison contain the bug fixes for smartd, bluetooth, LVM, etc.)
All I am saying is it's not soup yet.
