That would be awsome, but requires some pre-upload checks.

Then bfiles are no longer shared across repositories and the exactly same
file that is reused among lots of repositories uses memory where it doesn't
have to. *eek*

This logic should IMHO built into the application logic as a "purge" that
checks how often a file is hard linked and only purges it for real if it is
hard linked less than 2 times.

JMTC, cheers!
