[Ubuntu-16.04.3] Installer shows NVMe disks as "Unknown"

[Sujith Pandel]

Description:
Ubuntu installer shows NVMe disks as 'Unknown' as shown in the attached screenshot.

Reproducible:
Always

Steps:
1. Setup a server with at least one NVMe disks
2. Start Ubuntu-16.04.3 Server installation
3. Notice that the NVMe disk is listed as 'Unknown' by the installer.

Additional Info:
* Attaching the screenshot.

* During installation, udevadm does not have MODEL defined for NVMe disks.

* I can see udevadm having MODEL info on booting into OS post-installation. Hence I think initrd requires some changes w.r.t to udev. Please correct me if I am wrong on this suspicion.

Changing affected-package to udev, based on initial assessment as mentioned in Description.

[Sujith Pandel (sujithpandel)]

During installation:
# cat /sys/block/nvme0n1/device/model
Dell Express Flash NVMe 800GB

# udevadm info -e | grep -i model | grep -i nvm
<NULL>

Booting into OS, after installation:
# cat /sys/block/nvme0n1/device/model
Dell Express Flash NVMe 800GB

# udevadm info -e | grep -i model | grep -i nvm
root@ubuntu:/home/sujith# udevadm info -e | grep -i model | grep -i nvm
E: ID_MODEL_FROM_DATABASE=NVMe SSD Controller 171X (Express Flash NVMe XS1715 SSD 400GB)

Fixed in Ubuntu 16.04.4
NVMe disks are displayed as "NVMe disks" instead of Unknown.
