I would expect it to mostly work most of the time, but it's not
quite equivalent, nor is it guaranteed to work correctly under
all circumstances, and it's not always safe.(Think, for example,
of a situation in which the file system layout in the zone is
constructed from mountpoints that don't have the same
layout as viewed from the global zone. There was a time
when the SVR4 packaging tools used to be able to work out
how to put things in the right place for diskless client systems,
but that just shows how fragile this could be.)

Gotta second Peter's caution here. This is precisely the kind of inconsistency we've run into when using the -R option to pkg. I'm quite sure I _still_ don't understand it (and wait patiently for one of you to write the 'Definitive Guide' !! ) Meanwhile: Magical incantations, glue and duct tape.

There's probably a good reason why the manpages for pkgadd
and pkgrm explicitly tell you not to do this!
