Under FreeBSD-8, I'm battling this very problem.
The article linked-to by the above stackoverflow question:
Of course, my situation is slightly different in that I'm using
a vnet jail, (aka a vimage) not just a normal jail.
I'm finding that the sysvipc_allowed option is not being
inherited by vnet jails. My first inclination (since this is for
$work) is to just go in and change the default (did something
similar for enforce_statfs -- changing default to 1).
Not sure why a vnet jail isn't inheriting the option where the
parent whereas a normal jail does. That may not pertain to
your situation (haven't read the whole thread yet), but that
seems to be the case for us (and it's not the boot script either,
because I can see that the knob is twiddled to 1 before creating
the vnet jails yet the knob remains zero inside the jail afterward).
Again, this is on 8.x.
