DirID aren't that great either as I found out after I had to restore
a disk from a backup. :-( The dirID's all changed of course. I guess you need
a full pathname AND the volname,dirid,filname triplet to really be safe.
And anyone that looked into a alias can tell you that it does contain
the full path name. Damn you Apple! :-) (Do what I say not as I do. For years
Apple has been bellowing: "don't use full pathnames" What did they end up
using for aliases?)
