You might read the GNU tar info manual, Section ?6.10.2 Absolute File
Names? to understand, what's going on there. After that consider to use
the option ?--absolute-names?, when extracting the archive.
If you want that to be tar's default behavior, you can put that option in
the environment variable TAR_OPTIONS, when invoking GNU tar:
$ env TAR_OPTIONS=${TAR_OPTIONS:+"$TAR_OPTIONS "}'--absolute-names' \
tar xvfz tmp.tgz
