 How does this negatively impact you or other users?  As of Solaris 11
 Express, this requirement means that you have to run 'zfs create' once
 to create a ZFS filesystem that will be the parent of an arbitrry number
 of zones.

 I personally would not advocate a configuration where each zone is not
 on its own file system because a disk hog in one zone can deny service
 to other zones.

Be very careful here. If you allocate all of your Zones from a
single zpool and do NOT use quotas (and reservations) you can have one
Zone run the others out of disk space. Does the automatic (under the
covers) zfs create in Solaris 11 also automate setting reasonable
quotas and reservations ?

I don't want folks who are less familiar with ZFS to make that mistake.

 While I was working for a Fortune 10 company and
 introduced zones early in Solaris 10's life, I ensured that every zone
 had its own file system on a SVM soft partition.  This approach worked
 well for many years, but took a significant amount of effort to
 automate.  The integration of ZFS and Zones simplifies this type of
 architecture greatly.

We have used almost exclusively sparse root zones; for the space
efficiency, the global patching model, and the security of a read only
OS. I will be sorry to see the option of a sparse root zone go away.

Given the changes in packaging and patching between S10 and S11 and
(last I checked) lack of a direct upgrade path from one to the other,
I'd be really surprised if the above issues were all that significant.

In particular, the ZFS-based upgrade mechanism is substantially easier
to use and works much better than what we had for S10.  Forcing users to
put zones on distinct ZFS datasets seems to me like a trivial matter
that ends up simplifying and providing a lot of benefit.

That is not correct.

 3)zfs dataset requirement

How does this negatively impact you or other users?  As of Solaris 11
Express, this requirement means that you have to run 'zfs create' once
to create a ZFS filesystem that will be the parent of an arbitrry number
of zones.

I personally would not advocate a configuration where each zone is not
on its own file system because a disk hog in one zone can deny service
to other zones.  While I was working for a Fortune 10 company and
introduced zones early in Solaris 10's life, I ensured that every zone
had its own file system on a SVM soft partition.  This approach worked
well for many years, but took a significant amount of effort to
automate.  The integration of ZFS and Zones simplifies this type of
architecture greatly.

A reason that it is of great benefit is that with the new way it
is possible to create boot environments for each zone using ZFS clones.
The beadm + ZFS + Zones integration is much better than Solaris 10's
Live Uprade + ZFS + Zones.  Once Solaris 11 is released, I'll be happy
to talk about some other benefits of this new requirement.

 4)people just does not like changes

I think that is extreme.  People that don't like changes should probably
stick to old-world trades such as blacksmithing.  People that work in
any technology-driven business depend on change to make their operations
more efficient, to serve more customers, to improve their own products,
etc.  Change without reason is bad.  Change that offers benefits is
good.

If you don't want to endure the change that Solaris 11 has to offer,
Solaris 10 is still available and will continue to be available for
quite some time - there is nothing forcing anyone off of Solaris 10 for
the next several years.

to other zones.  While I was working for a Fortune 10 company and
introduced zones early in Solaris 10's life, I ensured that every zone
had its own file system on a SVM soft partition.  This approach worked
well for many years, but took a significant amount of effort to
automate.  The integration of ZFS and Zones simplifies this type of
architecture greatly.

A reason that it is of great benefit is that with the new way it
is possible to create boot environments for each zone using ZFS clones.
The beadm + ZFS + Zones integration is much better than Solaris 10's
Live Uprade + ZFS + Zones.  Once Solaris 11 is released, I'll be happy
to talk about some other benefits of this new requirement.


4)people just does not like changes

I think that is extreme.  People that don't like changes should probably
stick to old-world trades such as blacksmithing.  People that work in
any technology-driven business depend on change to make their operations
more efficient, to serve more customers, to improve their own products,
etc.  Change without reason is bad.  Change that offers benefits is
good.

If you don't want to endure the change that Solaris 11 has to offer,
Solaris 10 is still available and will continue to be available for
quite some time - there is nothing forcing anyone off of Solaris 10 for
the next several years.

I assume you are refering to Mike's response that zones require their own
seperate ZFS dataset going forward ? if so can you give some reasons
why this would make current s10 users unhappy when switching ?


thanks
