Debian 12 broken after first apt upgrade

[morsik]

Debian 12 is broken after first apt upgrade with installed on MDRAID.

apt upgrade causes to change /boot/grub2/grub.cfg and inject PARTUUID= which doesn't have a value causing futher boots to fail.

Removing grub-cloud-amd64 and /etc/default/grub.d/10_cloud.cfg fixes issue.

Original contents of that file exclusively disables UUID and forces PARTUUID which simply cannot be used in RAID setup.

# Use PARTUUID instead of UUID for root=
GRUB_DISABLE_LINUX_UUID=true
GRUB_DISABLE_LINUX_PARTUUID=

By the way grub-cloud-amd64 package is marked with "You don't want to use this package outside of cloud images" in debian repositories and bare-metal servers shouldn't use cloud images since it doesn't contain drivers for hardware...

The Debian image has definitely changed since my last install (around May/Jun) because other init scripts I had also stopped working, so I'm pretty sure this must be "new" (few months at most) bug.
