Sorry, but why is this restriction necessary?
The team thought that if an administrator created a zone to partition data with the intent to share data from that zone, allowing another zone to share it's root, probably didn't make sense.
Are you saying that this is something we should not actively prohibit ?
Let the administrator decide. All you achieve by adding arbitrary
restrictions is you will prevent someone from using Zones to solve an
issue they have, for which Zones would otherwise have been ideal, and
everyone loses. There are plenty of other reasons to use Zones which are
nothing to do with partitioning data.
If I understood correctly that there's some technical reason a directory
can't be shared by more than one NFS instance, then check for just that.
Don't add other unnecessary restrictions, particularly ones which break
current functionality which people may be using.
Just let whoever shares it first (global zone, or non-global zone) have the
share, and deny any attempt to share it by a second NFS instance. I can' see
any need for changing or removing the current behavior.
There isn't really any current behavior with respect to sharing in a zone :)
Well, there is. If you're changing it, then you need to make that clear.
I understand what you are saying and the zone boot restriction can be removed,
it doesn't effect the proposed new interfaces. My concern is inadvertent
"zone data leakage" ...
Explicitly sharing data isn't inadvertent.
