Comment (by rhaas):

 Actually the way Bruno does it may be better. The test really should be
 "did I get a hard link" (which is what I wanted) rather than "did I get
 something else that I got on this faulty system". One would have to check
 that eg python's stat called on a symlink which points to a file for which
 hard links exist does indeed report the number of hard links on the
 symlink and not those on the pointed to file. Ie.
 {{{
 touch TestFile
 ln TestFile HardLinkToTestFile
 ln -s TestFile SymbolicLinkToTestFile
 python <<EOF
 import os
 print os.lstat("SymbolicLinkToTestFile")
 print os.stat("SymbolicLinkToTestFile")
 EOF
 }}}
 which at least on my workstation gives "st_nlinks = 2" for the "stat" call
 and "st_nlinks=1" for the "lstat" call (see {{{man 2 lstat}}} for the
 difference between the two).
