Broke: /dev/sd*
Woke: /dev/disk/by-id/*
Bespoke: finding the correct device's SCSI host, detaching everything, then reattaching only the one host to make sure it's always /dev/sda. (edit) In software. SATA devices also show up as SCSI hosts because they use the same kernel driver.

I've had to use all three methods. Fucking around in /sys feels like I'm wielding a power stolen from the gods.

The SCSI solution requires making sure that you have the right terminator connector because of course there's more than one standard .. ask me how I know .. I think the Wikipedia article on SCSI says it best:

As with everything SCSI, there are exceptions.

Only if you're working with SCSI hardware. On Linux, SATA (and probably PATA) devices use the same kernel driver as SCSI, and appear on the system as SCSI hosts. You can find them in /sys/class/scsi_disk or by running lsblk -o NAME,HCTL.
