Changing dpkg behavior

[Tom Smith]

I'm using Ubuntu breezy. I needed to reorganize the filesystem so I did 
the whole backing up thing, reconfigured the partitions, created the new 
filesystems, restored my backups, and reconfigured grub and fstab.

Everything works fine now except that when I add or remove a kernel (I 
do a lot of custom kernels) it resets options in my menu.1st file that 
breaks grub--it's setting my "root" partition back to the old setting.

I've checked and checked and I'm unable to find a reason for this or a 
way to change this behavior.

Can anyone offer any suggestions for resolving this? Pointers to 
documentation would be great too!

Thanks in advance for your help!
