Re: tar and directory information

Also better be carefull with symlinks when untarring.

I had /usr/local as a symlink to another mounted drive and untarring a tarfile
containing 'usr/local/bin/FILENAME' in '/' overwrote the link.

This left me with a very small and useless /usr/local until I realised the mistake
and moved things to the right places.
