>From what used to be /lib/udev/path_id, which is now built into libudev- private for performance reasons. You can do that part manually with: sudo udevadm test-builtin path_id /sys/block/sr0 ** Summary changed: - udev uses wrong/conflicting /dev/disk/by-path link for scsi disks + /dev/disk/by-path link for scsi disks always has host "0", causing conflicts -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1321816 Title: /dev/disk/by-path link for scsi disks always has host "0", causing conflicts Status in “systemd” package in Ubuntu: Triaged Bug description: The /dev/disk/by-path links to scsi disks are supposed to be of the form "scsi-$host:$bus:$device$lun". The host portion is always zero, leading to duplicates from different hosts. It appears these numbers are pulled from ID_PATH, and I can't figure out where this variable comes from. I noticed this while playing around with the lio fake scsi target adapter. Here is the full udev info on a disk created on such an adapter. As you can see, it has been assigned scsi host id 13, so that is what it should be using for the $host digit, rather than zero.
