fedora core core 3 or core 5?

[Hart Larry]

Well, after upgrading from FC4 to FC5, I sure wish there were a way for 
installed packages to follow along.  Yes, I guess even windows, we must 
reinstall items, but it would sure be a wonderful linux improvement.
One of the file sharing programs, mutella, will not compile now because of a 
later gcc compiler.
Also, and I don't know how much its configureable, but tab completion here in 
TCSH is not working well.  Before, I could type some of a file name--and it 
would beep-and-read all the choices.  Well, now, seemingly if its not an exact 
match--and there are multiple choices, it just beeps--and doesn't read any of 
them.
