I assume this requires the IPC namespace to be created? That doesn't happen until the context is created, so none of the scripts would work for this particular problem. Having a non-executable one that does something like VSERVER_EXTRA_CMDS=( $_CHAINECHO /proc/sys/kernel/shmmax 134217728 ) is probably the only way to make it happen (with current tools). also using the sysctl interface instead of the deprecated procfs one (which might as well be hidden away :) is advised ... maybe special tool support will be added soon, so please double check with the tool maintainers I guess some nicer way to support it would be required, especially as more of these settings become available.
