[...] "by-id" has the disadvantage that it changes with the means of accessing the disk, namely if your driver uses the old (obsolete) ide API or is a new libata driver. Technically only "by-uuid" is relatively guaranteed to be stable (unless a partition gets cloned with dd), with "by-label" coming close (only bad if any disk or USB storage device duplicates an existing label, like "root").
