I wouldn't rely on that unless someone can confirm that its not
just coicidentally correct.  Do we know how /dev/sd* are assigned?

IIRC, some of this changes when I enable/disable ATA/SATA in one
of my machines' BIOSes.  I believe that using /dev/disk/by-uuid/*
avoids all this.  I typically leave a comment in fstab with something
more useful than /dev/disk/by-uuid/c8b8e289-4722-4230-af73-298dd7a42892.
