On systems with multiple 2.5-inch form factor PCIe SSD devices, locating the
physical drive can be made easier with symlinks that contain the drive bay
and slot information like this:
/dev/disk/by-path/PCIe_SSD_in_Slot_9_Bay_1-nvme0n1 -> ../../nvme0n1
/dev/disk/by-path/PCIe_SSD_in_Slot_9_Bay_1-nvme0n2 -> ../../nvme0n2
/dev/disk/by-path/PCIe_SSD_in_Slot_9_Bay_1-nvme1n1 -> ../../nvme1n1
The bay/slot information is read from the sysfs label attribute available for
each NVMe device.
v2: Incorporate Lennart's feedback
Do not shell out to "tr".
Create link in "by-path", not "by-location".
Remove "DRIVERS==nvme" check.
Do not make the rule vendor specific.
