I updated my pegasus installation to version 2.4.2 from the webpage.
It looks like the dagman dag of the pdax have an "exploding"
--relative-dir argument:

diff pegasus-2.4.0cvs/blackdiamond-0.dag pegasus-2.4.2/blackdiamond-0.dag:

Looking at PRE 00/ID2, it pads all the previous relative directories
(1, and 0) . At ID80, it pads around 89 directories.

Here's the invocation for pegasus-plan:

--rescue 100 -P CyberShake_LGU.pdax -s firefly -o local -D dags -f
