This depends of what "it" is. Your answer seems to be applicable to the original question. But it doesn't answer mine (hence a change of a subject line). Perhaps the answer to my question is -- it is a bad idea and it shouldn't be implemented. Fine. I still would like to know the reasons of why it might be considered a bad idea. So if is no to much to ask of this list -- I'd appreciated being educated on this subject. I'm also curious to know if what I'm requesting is reasonable but I should use a different "feature" to achieve what I want. To repeat *my* question: would it be possible to have a tunable parameter that would force all the FS traffic into a global zone the way this workaround does for NFS: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/fs/nfs/nfs_subr.c#4985 Since all the processes running in zones are nothing but regular processes I would like to have an option of making their FS related requests behaving like ones. Per my explicit request, of course. > I think the following is what we really need: > > 1. Allow non-global zones to be NFS servers > > 2.

Again, the above is all good and fine but it doesn't answer the question I asked (sorry -- I didn't change the subject before to avoid such a confusion).
