Subject: Directory copying using hard links?


Is there an "official" way of recursively copying directories so that 
individual files are hard-linked (if possible)? FileUtils has methods 
for creating single hard links (#ln) as well as for recursive copying 
(#cp_r). What's missing is the combination, essentially a call to

  cp -al src dest

However, I'm wary of using this instead of FileUtils.cp_r(src, dest) as 
the semantics are different. #cp_r makes a copy with path dest of a 
directory with path src. In contrast, cp -a src dest copies src into(!) 
dest. Now, File.dirname(File.expand_path(dest)) gives me the parent 
directory, but I'm simply not sure whether it works as intended in all 
cases.

Any suggestions?

Michael
