Hi All,
Created a small patch for 8.1 to add name support to /etc/rc.d/jail.
This doesn't upgrade /etc/rc.d/jail to the overhauled invocation of
8.0 but merely adds the ability to set a jail's name on start which
was added in FreeBSD 7.2 (May 2009).
Could this patch be considered to be applied to stable?
