I don't see anything you did wrong.  In addition to bu, make sure "pax"
and "perl" are in the command path.  I would think it would error and
abort, if not.

Unless your *pax* is somehow broken, since bu relies on it.

I just tested on BSD, with

  su
  mkdir /butest
  cd /usr
  bu -d /butest lib

And it worked fine.  Does the output on the screen show the links being backed
up?  Or did you check the log (usually in /var/log/bu/)?


If you don't get anywhere, try rebooting.  It is Linux :-).  I know that
sounds like a joke but actually, often when somebody reports some weird
behaviour with bu that nobody else has experienced, it has ended up
being some random Linux anomoly.  

Another thing you could do is try "rbu" to see if you get a similar
result.  rbu is the new rsync based bu that is intended to eventually
replace bu.

    http://hightek.org/bu/rbu-20080528

You have to have rsync installed.  If you try it, the command line is
slightely different.

    rbu d=/media/disk-1/bukubuinst lib

rbu does not have include/exclude lists, etc., yet.  I have focused
first on features that bu does not have.
