To be more specific: I think update-grub does that.  So if you change
to a different root device you would have to update /etc/fstab and then
run update-grub.

But, if you've changed to a different root device, all the older kernel
versions would also fail to boot if you didn't do that.

It's more likely that this package (or something else involved in
initramfs building) has been uninstalled for some reason.
