grubby vs. grub2-mkconfig

[Adam Pribyl]

There are at least two bugs that sum the confusion and remains in F17:

https://bugzilla.redhat.com/show_bug.cgi?id=755272
https://bugzilla.redhat.com/show_bug.cgi?id=768106

In short: kernel install adds option to grub.cfg using grubby, while 
grub2-mkconfig generates a different menuentries.

Why, if the boot loader is grub2, the menuentry is not generated at 
kernel install the same way as when generated by grub2-mkconfig?

The only reason I know is, that "people tend to modify grub.cfg manually", 
but with grub2 this is plain wrong anyway. Why do we support this messy 
setup then?
