Sorry for the late reply. I've slightly modified etc/rc.d/jail to
handle etc/jail/<name>.
For instance, instead of the following in rc.conf(5):
% jail_example_rootdir="/usr/jail/example"
% jail_example_hostname="jail.example.org"
% jail_example_ip="192.168.1.123"
% jail_example_exec="/bin/sh /etc/rc"
% jail_example_devfs_enable="YES"
% jail_example_fdescfs_enable="YES"
% jail_example_procfs_enable="NO"
% jail_example_devfs_ruleset="devfsrules_jail"
% jail_example_mount_enable="YES"
It is possible to use /etc/jail/example:
% rootdir="/usr/jail/example"
% hostname="jail.example.org"
% ip="192.168.1.123"
% exec="/bin/sh /etc/rc"
% devfs_enable="YES"
% fdescfs_enable="YES"
% procfs_enable="NO"
% devfs_ruleset="devfsrules_jail"
% mount_enable="YES"
I don't know where to document it though.
