Have you checked if -P or -U result in the intended behaviour?
Preserve pathnames. By default, absolute pathnames (those that
begin with a / character) have the leading slash removed both
when creating archives and extracting from them. Also, tar will
refuse to extract archive entries whose pathnames contain .. or
whose target directory would be altered by a symlink. This
option suppresses these behaviors.
-U, --unlink, --unlink-first
(x mode only) Unlink files before creating them. This can be a
minor performance optimization if most files already exist, but
can make things slower if most files do not already exist. This
flag also causes tar to remove intervening directory symlinks
instead of reporting an error. See the SECURITY section below
for more details.
Check "man tar" for "symlink". :-)
