Something that has been DONE and will NEVER be undone?
(Just kidding)
DID = Directory ID. MacOS expects every directory to have a permanent
unique ID because this allows for the beloved File System Specifier data
structure (aka FSSpec) to do magical file tracking even if you do things
like dismount volumes and re-arrange directory structures. The FSSpec and
it's descendants in the Alias Manager are a large part of why Mac users can
be so smug about not knowing or caring about full pathnames and
re-arranging folders.
Netatalk doesn't preserve DID's and so you can end up with programs that
normally perform magic with FSSpec's and the Alias Manager getting quite
confused. Quark, as an example.
