where to place patch for #163988

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

Hi,

I need a patch for bug #163988, but I don't know where to change the
code. The decision to create a link is made in lib/tarfn.c, but it is
overwritten by main/archives.c. So it should be the right thing to place
in archives.c the patch, but what's going on in lib/star.c? When is it
used?

The best thing I think is to try to create a symlink if link() fails. So
my patch would look this:

#v+
diff -ur dpkg-1.10.15/main/archives.c /home/Sources/dpkg-1.10.15/main/archives.c

+		 " creating symbolic link instead"),ti->Name);
+       if (symlink(hardlinkfn.buf,fnamenewvb.buf))
+	 ohshite(_("error creating symbolic link `%.255s'"),ti->Name);
+    }
     debug(dbg_eachfiledetail,"tarobject HardLink");
     newtarobject_allmodes(fnamenewvb.buf,ti, nifd->namenode->statoverride);
     break;
#v-

This isn't the final patch, but before I would go on, I'd like to know if
I am on the right way. Should there be an option to enable this behaviour?

Bye, Joerg.
