Working with grub2... update-grub in F16 ?

[linux guy]

I am trying to get the touchscreen to work directly on a Dell Duo.

I found the following article which uses grub2 to do this.

I have followed the directions and everything works fine until I reach
"update-grub".  Bash tells me there is no such command.

 $ yum whatprovides update-grub
No Matches found

The following ubuntu doc mentions update-grub as well, as well as lots
of other interesting tidbits on grub2.

How do I update grup.cfg on a Fedora 16 system ?

Thanks !
