You are saying if you don't explicitly use 'inherit-pkg-dir' in OpenSolaris and create the zone with 'create' then /usr, /sbin, /lib, and /platform are shared with the global zone?
I have used 'create' and not 'create -b' and I can install to /usr in the non-global zone. If it was a sparse zone then I wouldh't be able to because it would be shared. Am I missing something? I have installed Perl modules which go into /usr. /export isn't a shared directory either, so whether it is a sparse or whole root zone you could create /export/home. -- This message posted from opensolaris.org
