Сделал простейший пример:

$ gear --export-dir=$PWD

$ tar -vtf foo-1.0.tar
root         0 2021-01-09 00:45 foo-1.0/
drwxr-xr-x root/root         0 2021-01-09 00:45 foo-1.0/.gear/
-rw-r--r-- root/root        22 2021-01-09 00:45 foo-1.0/.gear/rules
-rw-r--r-- root/root       256 2021-01-09 00:45 foo-1.0/foo.spec
drwxr-xr-x root/root         0 2021-01-09 00:45 foo-1.0/src/
-rw-r--r-- root/root         0 2021-01-09 00:45 foo-1.0/src/a
lrwxrwxrwx root/root         0 2021-01-09 00:45 foo-1.0/src/b -> a

$ tar -C out -vxf foo-1.0.tar; echo rc=$?
foo-1.0/
foo-1.0/.gear/
foo-1.0/.gear/rules
foo-1.0/foo.spec
foo-1.0/src/
foo-1.0/src/a
foo-1.0/src/b
rc=0
