Nope, bad assumption; that is not what I mean. Please do as I ask and I'll 
explain after I see the result. Or read "man ls" to learn what symlinks are.

Did you recheck this just now, or are you correcting your prior posting 
from memory? If the first, then why didn't you run the other command I 
asked you to do above (since doing so would take about 10 seconds, less 
time than I am spending writing this sentence)? If the second, please 
recheck your work (that is, do what I request below) ... you will 
understand, I hope, that I am hesitant to rely on your demonstrably faulty 
memory.

Or did you have the actual text saved somewhere to check? If so, then 
please post it here.

This description is puzzling. Unless RH changed to using grub as its 
default bootloader and I missed that news ... possible, I suppose, but 
surely not way back in 7.2 ...the system you describe is not using *all* 
the default options. In any case, this is unlikely to be the source or your 
problem.
