Hello!
I am trying to provision a baremetall node using ubuntu24.04 and use
curtin to configure it. I have a well tested configuration file which
was used with curtin-21.3 and ubuntu20.04. However it doesn't work when
I try it on ubuntu24.04. It fails on dpkg-reconfigure grub-pc step.
There is software raid 1 configured and lvm root volume on it, here is
curtin configuration file:
```
storage:
version: 1
config:
- id: system_disk0
type: disk
ptable: msdos
model: KXG60ZNV256G TOSHIBA
serial: 31RY10AQYRU1
grub_device: 1
wipe: superblock
- id: system_disk0_part_1
type: partition
offset: 4194304B
size: 256056320000B
device: system_disk0
flag: bios_grub
wipe: superblock
- id: system_disk1
type: disk
ptable: msdos
model: KXG60ZNV256G TOSHIBA
serial: 31RY10AVYRU1
grub_device: 1
wipe: superblock
- id: system_disk1_part_1
type: partition
offset: 4194304B
size: 256056320000B
device: system_disk1
flag: bios_grub
wipe: superblock
- id: mddevice
name: md0
type: raid
raidlevel: 1
devices:
- system_disk0_part_1
- system_disk1_part_1
- id: lvm_volume_group
type: lvm_volgroup
name: system
devices:
- mddevice
- id: lvm_logical_volume_root
type: lvm_partition
name: lv_root
volgroup: lvm_volume_group
- id: lvm_root_format
type: format
fstype: ext4
volume: lvm_logical_volume_root
- id: lvm_root_mount
type: mount
path: /
device: lvm_root_format
```
So it configures successfully raid and lvm volumes. But then fails on
dpkg-reconfigure grub-pc (see attached log file).
The problem can be reproduced manually, so I can mount, chroot and then run:
```

```
install_devices looks correct and symlinks point to real nvme6n1 and nvme7n1 devices (not partitions). If I set `cloud_style_installation: false` - dpkg-reconfigure passes without errors, but it seems then grub doesn't trigger installation actually.
