Igor Ostapenko 30e6e008bc jail: Add meta and env parameters ... Each one is an arbitrary string associated with a jail. It can be set upon jail creation or added/modified later: > jail -cm ... meta="tag1=value1 tag2=value2" env="configuration" The values are not inherited from the parent jail. A parent jail can read both metadata parameters, while a child jail can read only env via security.jail.env sysctl. The maximum size of meta or env per jail is controlled by the global security.jail.meta_maxbufsize sysctl. Decreasing it does not alter the existing meta information. Each metadata buffer can be handled as a set of key=value\n strings: > jail -cm ... meta="$(echo k1=v1; echo k2=v2)" env.1=one > jls meta.k2 env.1 meta.k1 While meta.k1= resets the value to an empty string, the meta.k1 without the equal sign removes the given key.
