I can't remember if the device is needed. Man > sfdisk will fill in the details. From the man page: "-R Only execute the BLKRRPART ioctl (to make the kernel re-read the partition table). This can be useful for checking advance that the final BLKRRPART will be successful, and also when you changed the partition table ‘by hand’ (e.g., using dd from a backup). If the kernel complains (‘device busy for revalidation (usage = 2)’) then something still uses the device, and you still have to unmount some file system, or say swapoff to some swap partition." Interesting part about the swap partition. So it might go for both / and any swap partition.
