+Repos r1 and r2 should now contain hardlinked files:
+
+ $ nlinksdir r1/.hg/store
+ 2 r1/.hg/store/00changelog.i
+ 2 r1/.hg/store/00manifest.i
+ 2 r1/.hg/store/data/d1/f2.i

+ 2 r2/.hg/store/data/d1/f2.i
+ 2 r2/.hg/store/data/f1.i
+ 2 r2/.hg/store/fncache
+
+Repo r3 should not be hardlinked:
+
+ $ nlinksdir r3/.hg/store
+ 1 r3/.hg/store/00changelog.i
+ 1 r3/.hg/store/00manifest.i
+ 1 r3/.hg/store/data/d1/f2.i
+ 1 r3/.hg/store/data/f1.i
+ 1 r3/.hg/store/fncache
+ 1 r3/.hg/store/undo
+
+
+Create a non-inlined filelog in r3:
+
+ $ cd r3/d1
+ $ python -c 'for x in range(10000): print x' >> data1
+ $ for j in 0 1 2 3 4 5 6 7 8 9; do

+ 1 r3/.hg/store/data/f1.i

+ 1 r3/.hg/store/undo
+
+Push to repo r1 should break up most hardlinks in r2:
+
+ $ hg -R r2 verify
+ checking changesets
+ checking manifests
+ crosschecking files in changesets and manifests
+ checking files
+ 2 files, 2 changesets, 2 total revisions
