Bug Description

I can't boot from a PCIe NVME device on Xenial because the nvme.ko is missing from the initramfs. Can this please be added.

NAK. The patch is buggy and breaks initramfs generation for everything but nvme. It references the variable $root which does not exist, instead of $dev_node.

The $root issue was resolved subsequently in another upload.

I recently updated my kernel on my 14.04 install to the Xenial LTS kernel, and encountered the same issue. See: http://askubuntu.com/questions/786328/14-04-3-lts-xenial-kernel-upgrade-nvme-ssd-wont-boot

This bug is still present in 20.04, k5.4.0-113 at this writing.

Apparently the script looks *only* at /boot to decide which drivers are needed. When root (or /home) is on a separate nvme drive, the system won't boot until initramfs is updated manually (with nvme driver).

The fix seems pretty simple; just test the root fs type and include the drivers if different from those of /boot, then update initramfs.
