fallback if creating hard links fail (patch)

[Joerg Sommer <joerg@alea.gnuu.de>]

Hi,

I've a filesystem that do not support hard links across directories.
Currently we solve the problems while the dpkg unpack phase with this
patch:

     debug(dbg_eachfiledetail,"tarobject HardLink");
     newtarobject_allmodes(fnamenewvb.buf,ti, nifd->namenode->statoverride);
     break;
#v-

It's a simple fallback to symlinks if hard links fail. Is it possible to
add this patch to the debian package?

Bye, Jörg.
