I am trying to figure out how to get a script to figure out the hostname
of the jail that is starting without having to manual set that as a
command line parameter (as illustrated). It seems that the script is
getting executed in a clean environment, regardless of the exec.clean
setting. Is this a bug? The man pages aren't particularly clear on the
expected behaviour of this. I am running FreeBSD 10.2.
I would like to be able to set exec.poststart as a global default so it
doesn't need to be defined per jail.
Thanks,

exec.clean = 0 ;

exec.clean = 0 ;
