Comment 2 for bug 1808234

Further update, there is a new tool provided called update_iso.sh which would allow an ISO image to be updated for different kernel cmdline options such as rootfs_device=nvme0n1 and boot_device=nvme0n1 to change from the default of sda -> nvme0n1

Additionally when using the system update-host to assign personalities to unconfigured targets, you can assign the rootfs_device and boot_device on the commandline
