+Subject: [PATCH] Add hardlink resolver from util-linux
+
+The hard link resolver that is built into localedef cannot be run in
+parallel. It will search sibling directories (which are be processed
+in parallel) and perform a creation of a .tmp file and remove the
+original and move the .tmp file in. The problem is that if a probe
+occurs a hard link can be requested to the file that is being removed.
+This will lead to a stray copy or potentially, on a loaded system
+cause race condition which pseudo cannot deal with, where it is left
+with a hard link request to a file that no longer exists. In this
+situation psuedo will inherit the permissions of what ever the target
+inode had to offer.
+
+In short, there are two problems:
+
+1) You will be left with stray copies when using the hard link
+resolution that is built in while running in parallel with
+localedef.
+
+2) When running under pseudo the possibility exists for uid/gid
+leakage when the source file is removed before the hard link can
+be completed.
+
+The solution is to call localedef with --no-hard-links and separately
+process the hardlinks at a later point. To do this requires the
+inclusion of the hardlink utility found in modern versions of
+util-linux. Most host systems do not have this, so it will be
+included with the cross-localedef binary.
