Dear udev developers, Entries in /dev/disk/by-id are prefixed with e.g. ata-* or scsi-* or usb-* depending on the bus to which a disk is connected. This makes it impossible to switch disks between busses (e.g. hook an ATA disk to usbserial and just make it work). I can use by-uuid for partitions holding filesystems, but swap partitions are not exposed by-uuid, so those cannot be used across different bus-systems. IDs are either never guaranteed to be unique (meaning that there could be two disks with the same ID), in which case having the bus type there won't help. Or IDs are unique, then it'll be impossible for the same disk ever to appear on two busses at the same time. Therefore, the bus type doesn't need to be kept with the ID in order to guarantee uniqueness. I can't imagine a situation in which you'd want to access a disk only when it's connected to a certain bus. I *can* imagine a use case where you want to refer to a disk consistently, independent of the bus type. Maybe the solution would be to move /dev/disk/by-id to /dev/disk/by-bus+id and create /dev/disk/by-id to contain what it promises (and compatibility links for a while). Thoughts?
