i did it with gparted because it forces to re-read the partition-table
BEFORE reboot to make "boot /boot" successful

* umount /boot
* gparted
* move/resize boot-partition
* mount /boot
* grub-install /dev/sda

make sure you have a rescue-fallback before

in my case it was easy becasue 20 virtual machines, many of them
"only" backup / database-replication-slaves and all from the
same master which has foor boot a own virtual disk (one benefit
of virtual servers)

so i needed only one succesful run of this, made a dd-image of the first
guest, scp to the other ones, umount /boot and write dd-image to /dev/sda

with physical setups or if /boot is only a partition this is not so easy, but
the trick with resize/move should work too
