Comment 3 for bug 1128428

It could cause dataloss across filesystems. The reporter in question used it across chroots and symlinks and filesystems and it caused problems with /lib on his main fs. For an average use case, like deduplicating photos or music on a single filesystem, this is not an issue, and hardlinks are very desirable.

A newer hardlinks patch set was posted at <http://code.google.com/p/fdupes/issues/detail?id=8#c5>, but it has sat there for almost two years. It'd be very nice to have this feature back.

There's another Debian bug about this feature's being re-added: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=284274
