Bug#741342: /usr/sbin/update-grub: update-grub writes root=UUID= to grub.cfg for LVM2, renders machine unbootable

Package: grub2-common
Version: 2.02~beta2-7
Severity: critical
File: /usr/sbin/update-grub
Justification: breaks the whole system
Hello,
update-grub writes root=UUID=xxxxxx for LVM2 volumes to kernel command line.
This renders the system unbootable since it is not supported as far as I can tell.
Hence, if I replace root=UUID=af89a290-9c6f-4039-8d5c-95aa75654776 with
root=/dev/mapper/mdxinventi-root, the system boots fine.
P.S. It appears that 2.02~beta2-7 has been uploaded to unstable even if
the changelog indicates that it was targeted to experimental.
