Bug description:
[Impact]
The initramfs-tools hook-functions script cannot translate nvmeXnYpZ to
nvmeXnY block device, so it's failing and not building the initram disk.
Upstream solution is composed for at least 2 patches (it's a series,
but the 2 below are really the needed ones):
commit 3cb744c9
Author: Ben Hutchings <[email protected]>
hook-functions: Rewrite block device sysfs lookup to be generic
commit 8ac52dc0
Author: Ben Hutchings <[email protected]>
hook-functions: Include modules for all components of a multi-disk device
Instead of doing the backport, which is huge, we added another sed
substitution: currently the script has substitutions for sdX and hdX, in order
to convert sda1 to sda, for example. The new substitution converts nvmeXnYpZ to
nvmeXnY.
It's less intrusive than the full backport, since this is a SRU to Trusty
only.
[Test Case]
To be added.
[Regression Potential]
If the sed expression was somewhat broken, we could have an issue generating
initiramfs for generic block devices, like regular HDDs.
