Still not good enough for my USB-connected disks. Those have wwid with some naa.
, have a model
sysfs file (which is being ignored) but don't have a serial
sysfs. Drafted PR until minimally addressed
Force-pushed fixed version. I had made a gross mistake (hardcoded sda
) on the original commits; added a few fallbacks for disks without model / serial / wwid in that order, eventually using 'noserial' hardcoded.
This makes most disk devices at least appear in disk/by-id, even if they most probably won't match systemd's udev nomenclature, at least we have 'some' id. Using /dev/sdb et al directly is a recipe for disaster.
