NVMe boot drives not supported - failing in generating initramfs

Fixed in Debian

This solution was suggested by Szilard Cserey and further improved by Dan Streetman - thanks both!

Uploaded in Trusty upload queue. It is now waiting on SRU verification team approval to start building in trusty-proposed.

# Sponsoring note

[Nitpick]
- Add (LP: #1771557) in debian/changelog

[Note]
* The sed command seems pretty solid. The "*" is indeed a good idea, even if IMHO unlikely to exceed 2 digits if it happen the cmd will match any number that precedes "n", "p" and the end, even if exceeding 2 digits.
* I don't have an NVMe drive handy, but I know gpicolli did all the necessary validation pre-SRU.

[Manual verification]

Testing different nvme drive naming scenarios:

$ echo "nvme1n2p3" | sed 's/\(nvme[0-9][0-9]*n[0-9][0-9]*\)p[0-9]*/\1/g'
nvme1n2

$ echo "nvme11n22p33" | sed 's/\(nvme[0-9][0-9]*n[0-9][0-9]*\)p[0-9]*/\1/g'
nvme11n22

$ echo "nvme11n22p33" | sed 's/\(nvme[0-9][0-9]*n[0-9][0-9]*\)p[0-9]*/\1/g'
nvme11n22

$ echo "nvme111n222p333" | sed 's/\(nvme[0-9][0-9]*n[0-9][0-9]*\)p[0-9]*/\1/g'
nvme111n222

$ echo "nvme1111n2222p3333" | sed 's/\(nvme[0-9][0-9]*n[0-9][0-9]*\)p[0-9]*/\1/g'
nvme1111n2222

Hello Guilherme, or anyone else affected,

Accepted initramfs-tools into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/initramfs-tools/0.103ubuntu4.11 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-trusty to verification-done-trusty. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-trusty. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Thanks a lot Eric and Brian for handling the SRU process.
I just tested the packages initramfs-tools and initramfs-tools-bin version 0.103ubuntu4.11, from trusty-proposed, following the test procedure of this LP's description.

Everything is working fine, so I'll mark this as verification-done.

Cheers,

Guilherme
