I still seem to be missing something.

I've tried a number of variations on
export jail_smb_paramters=3D"allow.mount=3D1 allow.mount.zfs=3D1"
in /usr/local/etc/ezjail/smb but see no change in the output of sysctl =
inside the jail after stopping and restarting it.

I'm running ezjail 3.2.3 and freeBSD 9 STABLE.

Perhaps I am missing Drew's patch to the jail rc script?

Thanks again
