But if the hardlinks would be in an 'external files' directory

managed by the session manager only, you would still have

that choice when you make the archive.
Though I agree this is only based on convention...

You could make a symbolic link to a directory with hardlinks

managed by the SM. Then the SM would spread like a giant octopus ;-)
Well, only kidding...
I agree that the arguments against them are very strong.

But I must say, there is something seductive about them.
If you want to delete the originals without the fear of destroying

your sessions, go ahead. If you want to cleanup a session, tell

the session manager to delete the hardlinks for that session,

and delete the originals yourself.
If you want an archive, tell the SM to copy all the 'external files'

directories. Session management can exist in parallel with normal

filesystem activity.
And most importantly, never worry about those dreadful broken links...
But still I agree, on a more fundametal level, that hardlinks

are a bad idea.
