With the forthcoming update of sg3_utils to v1.48 (currently in Base:System, to be submitted to Factory soon), SCSI device identification and SCSI symlink generation by udev will change.
TL;DR: unreliable device identifiers will not be used by default any more, and /dev/disk/by-id symlinks for such identifiers will not be created by default, either. The policy can be changed by editing the udev rules in 00-scsi-sg3_config.rules.
To make sure this information isn't buried in the mailing list, I've created https://en.opensuse.org/SDB:SCSI_Device_Identification I've added kernel boot parameters as a means for rescue, in case this should cause regeression (I don't expect it will, but well...). The sg3_utils 1.48 update for factory is planned for week 41. Regards Martin
