Kernel modules may add their own parameters, which only exist when the
module is loaded.
These are typically headed under a parameter named after the module,
with values of
.Dq inherit
to give the jail full use of the module,
.Dq new
to encapsulate the jail in some module-specific way,
and
.Dq disable
to make the module unavailable to the jail.
There also may be other parameters to define jail behavior within the module.
Module-specific parameters include:
.Bl -tag -width indent
.It Va linux
Determine how a jail's Linux emulation environment appears.
A value of
.Dq inherit
will keep the same environment, and
.Dq new
will give the jail it's own environment (still originally inherited when
the jail is created).
.It Va linux.osname , linux.osrelease , linux.oss_version
