I have one of those idle questions that I can't answer and just can't forget.

In section 30.2.3.3.1 of the I&DS it says that VMB is one of the few files
that is located by an absolute LBN (in the boot block) and is not free to be
moved on our VAX 6000 system disk without running WRITEBOOT.

When a system disk is restored from backup, does BACKUP somehow preserve the
LBN of VMB.EXE or does it perform the functions of WRITEBOOT?  Obviously it
does something, or you couldn't boot from a restored system disk.
