I've looked at the grub.cfg file in /boot. It explicitly contains the
name of the old root partition in the Linux line of the stanza for the new
system. So after loading the kernel, it is started with the wrong
root partition as a parameter. This all happens before it has much of a
chance to look at iniitrd.

This is not an initrd problem. This is grub-update setting up the boot
configuration to go wrong unconditionally.
