Hmm that might work, but what will happen to the devices after you
remount the filesystem. Will /dev/mapper always be a tmpfs filesystem
after this?

Actually, I'm thinking another way to handle this might be to do a
'chroot /rootvol /sbin/vgmknodes' prior to the pivot_root instead of the
tar copy. There might be some way to handle it without the chroot, but I
think this will work.

I'll try this method out soon.
