[Bug 2056730] Re: noble-daily (20240310) cannot be installed offline

[Adam Fowler]

This bug also prevents an ubuntu-server noble autoinstall installation
with NVMe disks attached via PCIe. Noble 20230223.

My configuration was a simple storage: direct, with a disk: match
specifying 'smallest' and 'ssd: true' (I have 3 NVMe drives, one 128 GB
for OS, two 3.6TB for data.).

Mine is an offline install (true air gap).

Interestingly, the live CD autoinstall process correctly finds and
prepares the NVMe drive, installs the system and kernel fine. lsblk even
shows all 3 drives. lsmod shows nvme, nvme_core and nvme_common are
loaded - no nvme-cli or nvme-stas mentioned. It seems it is subiquity
adding those drivers.

Interestingly, the package search site shows noble has these packages:-
https://packages.ubuntu.com/noble/nvme-cli

I'm going to try the daily from last night to see if they are now
included.
