Have a look at the new variable I added to /etc/make.conf, if you check out ezjail now and do make install, all new jails should be installed with the new make.conf, for old jails just copy the make.conf from /usr/local/share/examples/ezjail/example/etc to your jail.
Wonderful! It works now. Thanks very much indeed. Now I can't help wondering how it worked for other people before. Jason
