The jail(8) method does have a allow_sysvipc on a per jail basis. To use
it you have to use the jail(8) method. The 9.1-RELEASE legacy method is
a work in process to incorporate the jail(8) parameters into the rc.conf
config statements.
About the allow_sysvipc parameter, this breaks the security the jail is
designed to provide and should NOT be used on any jails having public
internet access.
What are you trying to do that you think you need to use the
allow_sysvipc parameter?
