A quick search digs up that the path is created by this: https://github.com/systemd/systemd/blob/09541e49ebd17b41482e447dd8194942f39788c0/src/udev/udev-builtin-path_id.c#L349 . This code in that region was added in https://github.com/systemd/systemd/commit/ba86822db70d9ffd02ad78cd02b237ff8c569c7a but doesn't account for the fact that there may be multiple targets (each serving up a different ATA port 1)... Prior to that it doesn't look there was anything to build ATA paths at all? Additionally if my analysis is correct then this affects HEAD systemd-udev too.
I guess it would be good to know what the paths looked like back in 12.04 (perhaps they were SCSI based?) and whether you get any paths of that style on a system like 14.04 or 16.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611945 Title: /dev/disk/by-path not properly populated for (e)SATA port multiplier disks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1611945/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
