On SX:CE, it would be looking at the file system list with zonecfg for
inherit-pkg-dir.

In that case, it's harder to explain what you saw. Is it possible
that 'catalogue4' was actually created as a clone of some other zone
on that system you're comparing against?

I doubt it's possible to do that in the OpenSolaris distribution, as
that's not based on System V packaging. The tools are different
there.

"REFER" is documented on the zfs(1M) man page. It's the amount of
space accessible by the dataset and some or all of it may be shared
with another dataset. If you're interested in the amount of disk
space used, then the "USED" column is what you want.
At a guess, the difference between these two machines is that
'catalogue4' was likely created as a sparse-root zone, while
'catalogue2' was created as a whole-root zone. The clones of that
whole-root zone ('catalogue3' and 'test-drupal') use little disk
space, as most of it is 'referred' from 'catalogue2'.
This part of the output shows the relationships:
