This 685ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite 686ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding 687ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device 688ebc1a0e2SPeter Dufault# configuration around. 689ebc1a0e2SPeter Dufault 690ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.
