My system has:

-rw-r--r--  1 root root 15945815 Dec  1 21:24 

So yes, you should have one.

Depends.  If you used preupgrade to move from f15 to f16, it's probably 
a bug.  If you used yum to do so, I'm not sure that that is an 
"approved" method of does so at their own risk.

You could use dracut to build the initrd, but you're probably better off 
re-installing the kernel package.  Something like:

$ su -
# yumdownloader kernel
# rpm -ivh --force

You don't need to re-install grub, but you should double-check grub.conf 
before rebooting to the new kernel.

Also, I do believe f16 includes a move to grub2 -- at least, the tools 
are installed after I ran preupgrade & upgraded.  But my system was left 
still using grub.  That's not such a bad thing, since the grub2.conf 
syntax has completely changed, making us all grub noobs again.

There's also a wiki page somewhere that talks about post-upgrade 
cleanups one should perform to make sure old packages are thoroughly 
removed...ask in #fedora about that, or maybe someone will post the link.
