Booted to what? File copy can't be expected to work satisfactorily if source 
is running.

You have far more confidence in the competency of cp than I. Until last week, 
I'd never cloned a partition except by one of two ways: 1-DFSee (sector by 
sector); 2-MC, however it manages. Last time I tried MC I ran into trouble 
that probably was little different from what you just did, so last week I 
switched to doing file copies via rsync.

I suppose someone with a lot of experience could get away with sharing a 
/boot partition, but based upon your experiences of the past month I wouldn't 
expect that group to include you. I would have merged the content of the 
/boot partition into the /boot directory on the new /.

Leaving off some of those cmdline options could be a problem. I'm not 
familiar with all of them, and so would have included all I don't understand.

1-Do it again with rsync or a program designed specifically for cloning.
2-Merge /boot partition into the new /.
3-Either find out if any of those cmdline options can play a part in the 
problem and put back the ones you don't know you don't need, or add them all 
back except rhgb & quiet
4-Add option enforcing=0 to cmdline to ensure SELinux isn't in the way
5-Use the Grub on hd1,1 to start both, but for the clone include a hd1,16 
configfile stanza until you get it booted, then install Grub on sdb17 and 
afterward chainload from hd1,1 to hd1,16, where updates will ultimately be 
applied to grub.conf only for the clone on account of new kernels.
