> Log:
> Introduce the extensible jail framework, using the same "name=value"
> interface as nmount(2). Three new system calls are added:
> * jail_set, to create jails and change the parameters of existing jails.
> This replaces jail(2).
> * jail_get, to read the parameters of existing jails. This replaces the
> security.jail.list sysctl.
> * jail_remove to kill off a jail's processes and remove the jail.
> Most jail parameters may now be changed after creation, and jails may be
> set to exist without any attached processes. The current jail(2) system
> call still exists, though it is now a stub to jail_set(2).
Does this mean it is theoretically possible now to add/remove IP
addresses to/from a running jail? If yes, are you going to implement
the corresponding ifconfig feature? I would expect this in ifconfig,
as on Solaris ifconfig is able to do this with zones, I haven't looked
if the jail utility is able to do it.
Bye,
Alexander.
