The read-only
.Va security.jail.jailed
variable can be used to determine if a process is running inside a jail (value
is one) or not (value is zero).

There are currently two MIB related variables that have per-jail settings.
Changes to these variables by a jailed process do not effect the host
environment, only the jail environment.
