We have Alfresco installed under /opt/alfresco and the data under

Yep, that makes sense.
For now, I think I'll just store data right in the zone zvol until the
LX brand stabilizes a little more and they sort what they are doing
with mounting issue you brought up.
I'll get one of my colleagues better versed in Centos to add an
appropriate rc script to resolve that one.
I wanna test some things like FreePBX in the LX zones to see what
works and what doesn't. These LX zones are really opening up some
doors with VM containers. However, my current perception is that the
LX zones aren't any lighter on hardware resources than KVM zones.
Nothing scientific, just my gut feel at this point.
Try the test I did (building gcc) in a KVM (will all cores and plenty of
RAM) and then in an LX zone (with the same RAM cap). Monitor the system
load during the build. You will see that the zone is much kinder on the
host. Also remember these are zones, so you may have many more on a
system without loosing all your memory to KVMs whether they need it or
not. Although I haven't done any measurements, not loosing big chunks
of RAM should help with your ZFS ARC.
My test box is a pimped up consumer PC with a meager 32GB of RAM, so I
can only run a small number of KVMs at one time. On the same system I
will be able to run many LX zones concurrently.
