Why do you want to renumber it from 2 to 3?  You don't need to have
the minor numbers have the same order...  That said, what you're trying
to do looks rather painful...

In any case, I don't understand why sarge would have problems with it.

You must unmount.  (This is mentioned in the docs in the "Operating
Systems" section, although I will repeat this statement in other
sections as well).  Bootdisks might be helpful...
