Hi,

The order in which jails are started by rc.d/jail is the order in which
jails are listed in $jail_list which is fine.  On shutdown, jails are
stopped in the same order they were started which in some cases is not
fine.  If jail B depends on functionality provided by jail A, one would
like to start A before B but shutdown B before A.  Would it make sense
to reverse the order in which jails are stopped during shutdown by
reversing the nales in $jail_list?

The attached patch reverses $jail_list during shutdown.

Regards,

Paul Schenkeveld
