Now that you dropped the path selector as suggested back in July [1]
why not merge this with the ETERNUS DX entry?

If a lot of devices share the same configuration some flexibility is lost.
I do not have a single answer.
It's a tricky balance between to group devices and don't lose flexibility.

ETERNUS 2000/4000/8000 are very old and a different generation of devices,
the next year they are going to be declared "EOL" in Japan. In the rest of the
world it was at the beginning of 2015, IIRC.
